Micro and Nano structured Semiconductor Devices on Amorphous Substrates for Low-cost Energy Conversion, Sensing and Displays

Saif Islam


This talk will present an overview of several methods recently reported by the research community on the fabrication of single crystal semiconductor devices on amorphous surfaces. We will then present an experimental method to fabricate devices on single crystal substrates in the shape of micro-nano-pillars via both top-down and bottom-up techniques and then transfer them to low cost carrier substrates while simultaneously preserving the integrity, order, shape and fidelity of the transferred device arrays. The original substrates are repeatedly used for continual production of new devices and are minimally consumed. We also developed advanced flexible electrodes with nano-particle based composites and will present results of our studies on the interfaces between semiconductor devices and electrode based on composites of metal and conducting polymer (CP), metallization pastes, transparent conducting oxide, metal nano-particle and graphene enforced CP. This heterogeneous integration technique offers the ability to integrate any kind of single crystal semiconductor materials and devices on various substrates for large-scale applications in the areas of energy conversion devices, sensing, computing and micro/nanophotonics.
