Place:A718,SINANO

Abstract:

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, with unique band alignments that cannot be easily achieved in other materials. In these new materials, electronic, thermal, and optical properties can be quite different from those of conventional materials, with significant promise for applications in a variety of (opto)electronic devices.

Bio:

Dr.Joshua Zide is an Associate Professor in the Materials Science and Engineering Department at the University of Delaware. He received his BS with Distinction in Materials Science and Engineering from Stanford University and completed his Ph.D. in Materials at the University of California, Santa Barbara. His primary research interest is the nanoscale engineering of novel semiconductor and composite electronic materials for energy conversion and electronic devices. Zide has received the International Thermoelectric Society Goldsmid Award (2007), a Young Investigator Award from the Office of Naval Research (2009), the North American Molecular Beam Epitaxy Young Investigator (2011), a Department of Energy Early Career Award (2012), and the AVS Peter Mark Memorial Award (2014). He has authored or co-authored over 60 technical papers and several patents.
