Polycrystalline solid solutions of (Bi1 − _x_ Sb _x_ )2Se3 (_x_ = 0, 0.025, 0.050, 0.075, 0.100) were prepared using a facile method based on the conventional melting technique followed by annealing process. X-ray analysis and Raman spectroscopical measurements revealed formation of Bi2Se3 in single phase. The electrical and thermoelectric properties have been studied on the bulk samples in the ... إقراء المزيد
