Thermodynamic equilibrium of doped hydrogenated amorphous Si (a-Si: H) is explored using dark-conductivity measurements of small thermal perturbations. Raising the temperature increases the electron and hole densities owing to the activation of addit

Hall data obtained on intrinsic, phhosphorus and boron doped a-Si:H and a-SiC:H in the temperature regime 200 K ⩽ T ⩽ 400 K are introduced and discussed. The data confirm double sign anomaly. The Hall mobilities, μ H , are significantly smaller

Thermodynamic equilibrium kinetics of phosphorus (P) and boron (B) doped hydrogenated amorphous silicon (a-Si:H) are explored using dark conductivity measurements. Small variations in temperature of the semiconductor cause variations in active dopant
