The electrical resistivity, π, and Seebeck coefficient,_S_, of the system Sb2Se3 were measured in the ambient temperature range 323≤_T_≤573 K. Both parameters were found to be affected considerably by the temperature of annealing,_T_ a, in the range 493≤_T_a≤653 K and by the time of annealing,_t_ a, for periods extending to 16h. Additionally, both depended strongly on the ambient temperature. إقراء المزيد
