Title : Single crystalline semiconductor nanomembranes for ultra-compact optoelectronic applications
Abstract:
Miniaturization of photonic/optoelectronic devices offers tremendous performance gain. As the volume of photoactive material decreases, optoelectronic performance improves, including the operation speed, the signal-to-noise ratio, and the internal quantum efficiency. Single-crystal semiconductor nanomembranes (NMs) are free-standing thin films that can be released from a number of wafer sources are mechanically very flexible yet exhibit outstanding electronic/optoelectronic properties that are equivalent to their bulky counterparts. These thin flexible single-crystal materials can furthermore be placed, via transfer printing techniques, to nearly any substrate, including flexible polymers, thus creating the opportunity to high performance ultra-compact photonics and optoelectronics. In this talk, I will describe how various NMs can be fabricated and used to create high performance optoelectronic devices. Various optoelectronic devices such as reflector, photodetector, and light-emitting diodes will be covered.
