Abstract

In recent years, flexible electronic systems have gained increasing attention from scientific communities because of their potential to create new classes of applications (e.g. information display, medical diagnostic, X-ray imagers, flexible photovoltaic, flexible displays, structural health monitors, and other systems) that lie outside of conventional wafer-based electronics. With suitable choice of materials and design strategies, inorganic semiconductors can be used on mechanically compliant substrates for various electronic applications. Among various approaches to realize flexible electronics, deterministic printing assemblies of single-crystalline semiconducting nanomembranes on plastic substrates appear to be quite promising because it can catch two hares at once; mechanical flexibility and high electronic performances. This thesis is focused on materials and design strategies to realize complex integrated circuits (IC), and electro-mechanical sensors on mechanically flexible substrates using printed assemblies of high performance semiconducting nanomembranes. Furthermore, this thesis presents unconventional approaches to realize an array of micro-scale InGaN LEDs for mechanically flexible and stretchable optoelectronic systems with in-depth studies on electrical, optical, mechanical, and thermal properties of the system.
