First Principle Calculations of Hydrogen Defects in a-SiO2
Abstract
This report results from a contract tasking University College London as follows: The contractor will investigate electrical levels for radiation induced defects in amorphous SiO2. The objectives of this project are: (1) To develop an embedded cluster method for calculations of the electronic structure and spectroscopic properties as well as electron affinities and ionization potentials of point defects in crystalline and amorphous silica; and (2) To study the geometric electronic structure, stability and properties of proton and H(-) centers in alpha-quartz and amorphous silica.
