Abstract
Crystallization in amorphous Se films produced by flash evaporation technic has been studied from conductivity measurements on the temperature range 313 to 353K. The experimental results show an heterogenous nucleation and that the crystallization depends upon thickness ; they allow us to determine the parameters which characterise this phonomenon : growth and nucleation rates, concentration and mean size of the crystallites in good agreement with microscopy studies, as well as the growth rate activation energy.
