"Transfer printed crystalline Semiconductor Nanomembranes for flexible optoelectronics, electronics, and Si photonics"
Weidong Zhou Department of Electrical Engineering, University of Texas at Arlington

Abstract
Crystalline semiconductor nanomembranes (NMs), which are transferable, stackable, bondable and manufacturable, offer unprecedented opportunities for unique electronic and photonic devices for vertically stacked high density photonic/electronic integration, high performance flexible electronics, and adaptive flexible/conformal photonics. Over the last few years, we have been carrying out research on various photonic and electronic devices, based on transfer printing techniques and heterogeneous integration of III-V/Si material systems. In this talk, I will highlight our research progresses in the areas of flexible optical filters, LEDs, solar cells, photodetectors, and other photonic and electronic devices on flexible plastic substrate as well as on silicon substrate. The potentials and prospects of nanomembrane materials will also be discussed.

Bio
Dr. Weidong Zhou (PhD, University of Michigan) is an associate professor of Electrical Engineering at the University of Texas at Arlington. Dr. Zhou’s nanophotonics lab (nPLab) is carrying out various active research projects in the areas of photonic crystal infrared photodetectors, silicon based detectors, sources, and modulators, bio-inspired photonics, flexible photonics and electronics, and cost effective solar cells, etc, based on photonic crystals, semiconductor nanomembranes, quantum dots, and other nanoscale structures.
