Recent studies show that low dimensional systems (nanowires) exhibit enhanced and intriguing mechanical and thermoelectric properties when subjected to strain. The study carried out in this post-doc project will focus on challenging issues related to fabrication, characterization and modeling of nanowire based devices under strain. Size dependence of mechanical properties such as fracture strain/stress of silicon & silicon-germanium nanowires (NWs) will be investigated. The present proposal falls in the context of Silicon & Silicon-Germanium (Si & SiGe) nanowire electronics under extremely high strain levels and addresses the following fundamental and applied scientific questions related to mechanical, electrical and thermal properties: -What is the ultimate strain level that can be developed in Si and SiGe-NWs? -How do electrostatics and mobility respond to extreme strain levels? -What is the ultimate reduction of thermal conductivity under extreme tensile strain?
