EPR studies on amorphous Ge‐Al and Ge‐Cu films

摘要

Electron paramagnetic resonance in amorphous germanium (a‐Ge) alloy films containing varying concentrations of Al and Cu has been studied. The concentration of free spins (dangling bonds) is found to decrease rapidly on alloying to less than 5×1017/cm3for about 8 at.percent; Al and 10 at.percent; Cu concentrations. Thegfactor and line shape remain unaffected on alloying. The linewidth, however, shows minor changes.
