D C. conductivity and thermoelectric power ofa-As2te3 films

الملخص EN

a- A2Te3 films prepared by thermal evaporation at different annealing temperature Ta in the range (303-473) K.

and thickness in the range (200-350) nm .D C.

Conductivity and thermoelectric power were studied as a function of temperature for a- As2Te3 films.

Electrical conductivity of a- As2Te3 thin films decreases with increasing Ta.

The activation energy Ea increases with increasing Ta.

The thermoelectric power measurement confirmed that holes were predominant in the conductor process.
