Abstract

Differential scanning calorimetry (DSC) studies of P-doped hydrogenated amorphous silicon (a-Si:H) show characteristixc behaviors of glass transition phenomena. The glass transition temperature (Tg) detected by DSC for each sample well agrees with the equilibration temperature (TE) determined by the temperature dependence of dc conductivity. Regarding the influence of hydrogen content, Tg decreases and heat energy absorbed in this reaction increases, as hydrogen content increases. The interpretation for these phenomena is successfully attempted by the simulation based on the excess heat capacity model caused by the equilibrium process of defects.
