Electron transport and superconductivity in amorphous Sb and its alloys

Abstract

Amorphous Sb and its alloys are shown to be similar to amorphous Ge from studies of resistivity and electron tunneling. The localization behavior for impurity states in amorphous Sb follows the same general rules as observed for the localization of impurity states in amorphous Ge. Even though crystalline Sb is a semimetal, amorphous Sb is found to be a semiconductor with properties similar to the amorphous tetrahedrally bonded semiconductors.
