Hello World.
My name is Kevin Garrity. I can be found in Becton 313. My email address is the standard first.last@yale.edu
I am working on first-principles DFT calculations to help understand the deposition of strontium on silicon (100), which is the first step in growing SrTiO3 on silicon. I am interested of these particular materials because of their application to the so-called high-K dielectric problem facing the semiconductor industry. The goal is to replace the silicon dioxide (or soon to be hafnium/silicon oxide) in transistors with a material that has a higher dielectric constant, which will help reduce quantum mechanical leakage currents and allow further device miniaturization (resulting in faster, more efficient computers).
Sr (yellow) on Si (light blue).
When the Sr binds to Si, Sr donates electrons from the red area in this image...
... which go to the blue areas in this image, filling the Si dangling bonds.
