Abstract:

 

The effect of g -radiation on the electrical  conductivity, switching, and optical properties of the chalcogenide  amorphous system Gex(As2Te3)100 - x (where x = 0,1,5,10 atm %)  have been studied.  The results show that the radiation causes a shift  of the optical gap,as well as a change in the electrical activation  energy and the threshold voltage.  As the g -doses increase, the  values of the allowed indirect optical energy gap Eopt for the  different compositions decreases and the tail energy width increases.
