Abstract
The electric transport mechanisms in a-Si : H junctions have been studied as a function of impurity doping level. At low doping current is limited by generation-recombination in the depletion layer. At high doping (10-3 Ω-1 x cm-1 on the junction sides) tunnel current are observed with an effective tunneling gap of 0.8 eV. The differential conductance around the origine is 3.10-1Ω-1cm-2.
