Chalcogenide Semiconductor Thin Films

Research in chalcogenide semiconductor thin films explores the synthesis, characterization, and application of materials containing at least one chalcogen element (sulfur, selenium, or tellurium) and a metal or metalloid. Investigations focus on understanding the fundamental relationships between material structure, electronic properties, and optical behavior. Techniques employed include various deposition methods to create these films, such as sputtering, evaporation, and chemical vapor deposition. Studies examine their potential in diverse electronic and optoelectronic devices, including solar cells, photodetectors, and phase-change memory.

This research holds relevance for Arkansas's technology sector, particularly in the development of advanced materials for energy applications like solar power generation. The state's growing interest in renewable energy and advanced manufacturing can benefit from innovations in efficient and cost-effective photovoltaic materials. Furthermore, understanding the optical properties of these films can contribute to advancements in sensing technologies relevant to environmental monitoring and public health applications.

This area of study involves collaborations with researchers in semiconductor materials and devices, photonic and optical devices, and 2D materials. Expertise is distributed across multiple institutions within Arkansas, fostering a broad base of knowledge and capability in thin film material science and device engineering.
