Thermal, self-heating and kink effects in a-Si:H thin film transistors

We report on self-heating, thermal and kink effects in a-Si TFTs. These effects become crucial for gate lengths of 4 microns and shorter. Our data show that self-heating effects in TFTs might reduce the highest operating temperature for AMLC displays by up to 30 to 40/spl deg/C for a 4 /spl mu/m gate device and even more for shorter devices.
