The stability of VHF-GD a-Si:H for different deposition temperatures has been investigated by photothermal defection spectroscopy(PDS).Parameters of the defects in a-Si:H
such as
correlation energy and density of gap states.have been obtained by the numerical simulation of PDS. The results indicate that the metastable defects shift toward to the deep of the gap and correlation energy increases with the light illumination time. The Fermi level and conductivity have been recursively calculated under the electroneutrality condition
which are in fairly agreement with the experiment.The validity and reality of the simulation have been discussed.
