Chungbuk National University Researchers Develop a Novel Method for Fabricating High-Quality and Non-Toxic Colloidal Quantum Dots
Image title: Multifaceted passivation strategy for developing AgBiS2 colloidal quantum dots

By utilizing an innovative new strategy, researchers significantly enhance the efficiency of solar cells made from AgBiS2 colloidal quantum dots.
As an alternative to toxic lead-based colloidal quantum dots (CQDs), AgBiS2 CQDs have garnered considerable attention for the development of non-toxic solar cells. However, these solar cells suffer from lower power conversion efficiency than their lead-based counterparts. To address this, researchers have developed a novel strategy to develop high-quality AgBiS2 CQDs and stable CQD inks. This strategy holds great potential for developing high-efficiency solar cells and ultrafast optoelectronics.
Solution-processed semiconductors are a special class of semiconductors that can be synthesized using chemical solutions. They have gained significant attention in the fields of energy conversion and optoelectronics. Among these are colloidal quantum dots (CQDs), which are nanoscale materials that can be used to make optoelectronic semiconductors. In these semiconductors, light is converted to electricity through the generation of charge carriers. CQDs offer a unique advantage for developing solar cells with high optical-to-electrical power conversion efficiency (PCE), thanks to the quantum confinement effect that allows tuning of their absorption spectrum from visible to infrared.
Conventional CQDs are typically made from lead-based compounds, which limits their commercial viability due to the high toxicity of lead. As a result, there has been a growing interest in nontoxic CQDs made from ternary compounds, such as Bismuth Silver Sulfide (AgBiS2) CQDS. Despite their high absorption coefficient, AgBiS2 CQD solar cells have a relatively lower PCE than their lead-based counterparts. This is due to higher nonradiative recombination losses, where charge carriers become trapped in defects within the material, dissipating energy as heat instead of electricity. Many strategies have been proposed to solve this issue, however, the surface properties of AgBiS2 CQDs are still not understood and an efficient solution-based and surface-tailored method for developing stable CQD inks is yet to be discovered.
To address this gap, a team of researchers led by Assistant Professor Han Seul Kim from the Department of Advanced Materials Engineering at Chungbuk National University, Korea, developed a novel method for synthesizing high-quality AgBiS2 CQDs. In this joint research effort, Chungbuk National University researchers revealed and designed the mechanism through simulation and a Korea University research team produced it through experimentation.
“Conventional methods to develop AgBiS2 CQD films introduce defects on their surface, increasing the trapping of charge carriers and consequently the nonradiative combination loss. We devised a novel quadruple-ligand ensemble using a solution-phase ligand exchange strategy to passivate CQD surfaces and address this issue” explains Dr. Kim. Their study was made available online on January 05, 2024, and published in Volume 14, Issue 7 of the journal Advanced Energy Materials on February 15, 2024.
At the core of their method is an innovative multi-faceted passivation strategy, in which a unique quadruple-ligand ensemble consisting of Silver Iodide (AgI), Sodium Iodide (NaI) Silver Bromide (AgBr) and Sodium Bromide (NaBr) is utilized in a special solution-phase ligand exchange process (SPLE). During this process, the ligands effectively replace the defects on the polar (100) and nonpolar (111) facets of AgBiS2 CQDs. This results in the multifaceted passivation of the CQD surface, ultimately resulting in the formation of a stable CQD ink.
To understand the role of each ligand, the researchers utilized the powerful Density Functional Theory for simulations. Their analysis revealed that the Ag ligands initially deposit on the two facets and further induce additional adsorption of Na ligands, resulting in multifaced passivation. This synergistic passivation results in lower trapping of charge carriers, thereby boosting PCE.
The researchers teamed up with a group from Korea University to implement this strategy in fabricating thin film AgBiS2 CQDs solar cells and photodetectors. The solar cells demonstrated a remarkable PCE of 8.1%, representing a substantial 53% increase compared to conventional CQD solar cells. Moreover, the photodetectors exhibited the fastest reported response time of 400 nanoseconds.
“These results highlight the potential of our strategy for fabricating high-quality AgBiS2 CQDs and therefore realizing high-performance optoelectronic devices. Moreover, our method is generally applicable to quantum dot material synthesis,” remarks Dr. Kim. “Our research opens the door to several real-life applications, including highly efficient solar energy harvesting, ultrafast sensors, and high-end imaging systems for medical diagnosis.”
Overall, this groundbreaking strategy contributes to the development of high-efficiency solar cells and enhanced optoelectronic devices, paving the way for improved environmental sustainability and potentially transforming energy consumption and electronics usability.

Chungbuk National University Team Decodes Growth Process of Plasma-Assisted Epitaxial Silicon

Researchers manipulate defects to enhance electrical properties of Plasma-Assisted Epitaxial Silicon and uncover its growth dynamics
Plasma-assisted epitaxy can grow single-crystal silicon (plasma-epi Si) at low temperature of 200 °C, whereas conventional single-crystal silicon is grown by the Czochralski method at approximately 1500 °C. However, plasma-epi Si usually shows undesirable electrical properties. Researchers from Korea have now explored the growth dynamics of plasma-epi Si to reveal a two-stage evolution. They also propose strategies to tailor the nanostructure for various applications, ranging from electronic devices, gas sensors, and lithium-ion batteries.
The fabrication of microelectronic components of widely used electronic devices involves several thin-film deposition processes. One of them is epitaxy, which can be used to grow thin crystalline films with a specific crystal structure and direction. When silicon (Si) is grown epitaxially using plasma-assisted chemical vapor deposition (denoted as plasma-epi Si) a new material with a customizable nanostructure is obtained.
Although plasma-epi Si is a novel material, it has not garnered much scientific attention due to unsuitable electrical properties. However, since the nanostructure of plasma-epi Si can be easily manipulated, it can be used in various applications. In particular, nanometer-scale voids can be introduced, with control over both the quantity and arrangement.
In a new study published in Small Structures on 19 December 2023, Associate Professor Ka-Hyun Kim from Chungbuk National University and his team of researchers have investigated the growth dynamics of plasma-epi Si grown under various process conditions. “This research provides general knowledge on the defect nanostructure in crystalline silicon. In a departure from the conventional approach, we present a study on the hydrogen-incorporated nanostructure of plasma-epi Si and its growth dynamics, correlating the hydrogen incorporation with the defect nanostructure of the material,” explains Prof. Kim.
In the study, the nanostructure of the plasma-epi Si was manipulated by exploring different deposition conditions to grow films of different nanostructures. One of the examined conditions involved altering the relative flow ratio of the constituent gases, which influenced the concentration of atomic hydrogen. Theoretical simulations were conducted to support the experimental results.
The experimental observations of the study revealed a two-stage evolution of the nanostructure, characterized by different dominant nanostructure defects. In the initial stage, the nanostructure can be manipulated via the deposition conditions, resulting in a porous and interconnected structure that is dominated by voids, because of high hydrogen incorporation. In the subsequent bulk growth stage, the material growth is less sensitive to the deposition conditions, but evolves with film thickness, leading to the prevalence of isolated defects in the evolving nanostructure.
Based on these findings, the researchers propose distinct deposition strategies for different applications. To enhance carrier transport properties in electronic applications, it is recommended to suppress strain during the initial growth stage, alongside controlling isolated bulk defects. On the other hand, for applications involving bottom-up-grown Si, a consistent supply of strain during growth is suggested.
“Crystalline Si is a material widely used in the semiconductor and solar industries. Through this development of bottom-up-grown plasma-epi Si, we can expand the application of crystalline Si into various fields such as gas sensors, lithium-ion batteries, hydrogen storage, and even explosives,” envisions Prof. Kim.
In summary, these findings elucidate the growth dynamics of plasma-epi Si, a new Si-based material with a customizable nanostructure and porosity. Additionally, the researchers have suggested different strategies for optimizing the plasma-epi Si growth process tailored to specific applications. These results thus contribute to a deeper understanding of this material and pave the way for the identification of diverse applications for bottom-up-grown porous Si!

Unlike traditional memory devices that store information in a static format, memristors adapt their resistance based on the history of applied voltages, mirroring the adaptive learning process of synaptic connections in the brain that strengthen or weaken over time. Advancing memristor technologies, this study goes a step further by presenting a novel triple-mode memristor based on Cs2AgI3, featuring 1D [AgI4]3- tetrahedral nanowire structures. This novel theoretical/experimental design on the material not only captures the essence of both short-term and long-term synaptic changes, but also crucially modulates the migration of specific ions within the Cs2AgI3 structure in response to the amount of applied bias voltage. This unique mechanism allows for the precise simulation of synaptic behaviors, ranging from rapid, short-lived responses to consistent, long-lasting adaptations, directly linking the control of ion movement to the emulation of synaptic plasticity. When integrated into artificial neural networks, it demonstrates high accuracy, highlighting its superior performance as synaptic device. This breakthrough paves the way for next-generation neuromorphic computing, bringing us closer to new era of computing that learn and adapt like human brains.
