Hot Electron Conduction in a-Si:H/a-Si0.2C0.8:H Super Structure

Abstract
A-Si:H/a-Si0.2C0.8:H super structures were fabricated by glow discharge method. The barrier layer using a-Si0.2C0.8:H was typically 40 Å thick. The thickness of the well layer consisting of doped n-type a-Si:H was changed from 17 Å to 100 Å. The construction of super structures was confirmed by X-ray diffraction. Generation of hot electrons using a newly devised super structure was verified experimentally for the first time.
