Abstract :
We have identified atomic scale processes involved in the so called "interface trap transformation" process. These changes involve the generation of a silicon "dangling bond" defect called Pb1. This defect is somewhat different in electronic density of states and slightly different in physical structure than the dominating radiation induced Si/SiO2 interface trap defect, the Pb0 center
