We found that both undoped and P-doped a-Si1-xCx:H films exhibit thermal-equilibrium phenomena similar to those in a-Si:H although they have much higher defect densities. By heating the samples in situ during ESR measurements, we were able to directly observe the density of dangling bonds in both a-Si:H and a-Si1-xCx:H as the samples move from a frozen-in state into a temperature-dependent equilibrium. The influence of surface states and long-term drift of exposed surface on the thermal-equilibrium process has also been extensively investigated. © 1988 The American Physical Society., 金沢大学設計製造技術研究所 / 金沢大学理工研究域電子情報通信学系}, pages = {8371--8376}, title = {Thermally induced metastable defects in hydrogenated amorphous silicon and silicon-carbon alloy films}, volume = {38}, year = {1988} }
