Electron localization in the insulating state: Application to crystalline semiconductors
Electron localization in the insulating state: Application to crystalline semiconductors
We measure electron localization in different materials by means of a ``localization tensor'', based on Berry phases and related quantities. We analyze its properties, and we actually compute such tensor from first principles for several tetrahedrally coordinated semiconductors. We discuss the trends in our calculated quantity, and we relate our …
