## Abstract The structural disorder model of amorphous semiconductors, near the amorphous to crystalline transition, recently proposed, is generalized for triply coordinated As. The model is able to explain at least qualitatively the change in enthalpy and the configurational entropy during transit
The slope of (ahยขo) 1/2 vs. hยขo depends on the product of the oscillator strength of the transition, the deformation potential and the mean deviation of the atomic coordinates. In a perfect crystal, this deviation is characterized by phonons, whereas in amorphous silicon (a-Si) and amorphous germani
