Synthesis and Characterization of Nano-to Meso Scale Ordered Structures in the Si1-xGex Alloy System

Abstract

This dissertation describes investigations of structural ordering in the Si-Ge material system from nano-to-meso scale in order to modify electronic and thermal transport properties for potential improvement in thermoelectric or nanoelectronics applications.We first present the synthesis and characterization of mono-layer scale chemically ordered Si1-xGex alloys. Here, metastable ordering to an L11-like structure, occurring during
