Fundamental Studies of Model Electronic Devices Incorporating Self-Organized Quantum Dot Nanostructures

Abstract

The objective of this research program was to perform fundamental studies to establish the utility of self-organizing Si/Ge nanostructures for eventual use in quantum-dot (QD) electronic devices. These studies consist of three major components: a) optimize the size and distribution of the three-dimensional pyramidal clusters that form in SiGe/Si(001) films and multilayers under defined growth conditions; b) design and simulate basic device building blocks and test structures for semiconductor devices that incorporate SiGe QDs, and c) make electronic and optoelectronic properties measurements and correlate these to structural and compositional ones to test the utility of arrays of pyramidal clusters for QD electronic devices.
