Novel Semiconductor and Epitaxial Nanocomposite Materials for Energy Conversion Applications

Joshua M.O. Zide
Assistant Professor
Materials Science and Engineering
University of Delaware

Advances in electronic materials (specifically, semiconductors and nanocomposites) enable new device technologies and improve the properties of existing technologies. In this talk, I will present efforts within my group on the growth of new materials by molecular beam epitaxy and the resulting advances in solar cells, thermoelectrics, and optoelectronics. Specifically, I will discuss two material systems: (1) nanocomposites consisting of metallic nanoparticles (such as ErAs and TbAs) within III-V semiconductors (such as InGaAs and GaAs), and (2) dilute bismuthide semiconductors in which bismuth is incorporated into III-V materials to reduce the bandgap significantly. In these new materials, electronic, thermal, and optical properties can be quite different from those of conventional materials.
