Themoelectric power and conductivity of As-doped a-Si:H:F

Abstract
Thermoelectric power and conductivity measurements on As‐doped a‐Si:H:F have been combined with exact computations of conductivity and thermopower to determine the midgap density of states (1016 eV−1 cm−3) and maximum mobility (11 cm2 V−1 sec−1). The mobility edge is found to lie significantly deeper in the gap than in a‐Si:H.
