Hole Transport in Glow-Discharged a-Si:H Films Compensated with Boron

Abstract
In lightly boron-doped a-Si: H films electrons become highly dispersive in time-of-flight measurement while holes clearly show a non-dispersive transport, in drastic contrast with observations in undoped or lightly phosphorus-doped films. Mechanisms responsible for the drastic change in the electronic transport characteristic between undoped or phosphorus-doped slightly n-type and lightly boron-doped films are briefly discussed.
