Hydrogen is a ubiquitous impurity in diamond but in contrast to other group IV materials the
microscopic structure adopted in bulk material has largely remained elusive. It has therefore …

The authors review what has been learned concerning the electrical and annealing
properties of point defects in high-energy electron or proton irradiated Si from deep level …

Defects in crystalline silicon consisting of a silicon self-interstitial atom and one, two, three,
or four hydrogen atoms are studied within density-functional theory (DFT). We search for low …

Native defects in Si are readily created during a variety of processes. They diffuse rapidly
and interact with themselves, with each other, and with many impurities, in particular …

Technologies that could further improve commercial silicon solar cell cost effectiveness are
explored in this thesis. The screen printed p-type silicon solar cell efficiency is limited by two …

An implanter without an ion mass analyzer has been used to successfully fabricate silicon
on insulator (SOI) materials by H 2 O+, HO+, and O+ ion implantation using water plasma …
