Abstract

The influence of the crystalline volume fraction of hydrogenated microcrystalline silicon (mc-Si:H) on the performance of thin-film transistors (TFTs) processed at temperatures below 180 °C was investigated. TFTs employing mc-Si:H channel material prepared near the transition to amorphous growth exhibit the highest electron charge carrier mobilities exceeding 50 cm2/Vs. The influence of the crystalline volume fraction of the intrinsic mc-Si:H material on the transistor parameters like the charge carrier mobility and the contact resistance will be discussed.
