摘要：

The temperature dependence of the structural properties of a-SiGe:H and a-CSiGe:H films has been studied. The samples were characterized by differential scanning calorimetry, conductivity measurements, electron-spin resonance, infrared, optical, and photoacoustic spectroscopy. The disagreement of previous results of differential scanning calorimetry on hydrogenated amorphous semiconductors samples (a-Si:H and a-Ge:H) is examined and discussed. The equilibration temperature determined by the temperature dependence of dc conductivity agrees well with that of the first exothermic process detected with differential calorimetry. The second exothermic effect occurs when hydrogen evolution starts, as confirmed by electron-spin resonance and infrared spectroscopies.
