查询词典 diffusion coefficient

The leakage current of poly-Si TFTs is owing to the high drain electric field and large trap state density at drain junction. In this thesis, we found the silicon nitride film as the diffusion barrier prevents the hydrogen atoms downward diffusion and accumulated at the channel to further reduce the trap state density.
