Electrical properties of a-Se85−xTe15Snx thin films

Electrical and optical properties of thin film of a-Se70Te30 nanorods

“…Various workers [24][25][26][27] reported the temperature dependence of conductivity in amorphous semiconductors and studied the conduction mechanism in these chalcogenides. The conduction in chalcogenide glasses is intrinsic [28,29] and that the Fermi level is close to the midway of the energy gap.…”

Compositional dependence of thermal stability, glass-forming ability and fragility index in some Se–Te–Sn glasses

“…In order to overcome this problem, to enhance the thermal stability and to enlarge the domain of applications, it is necessary to add a third element (like Sn) as a chemical modifier which expands the glass forming area and also creates compositional and configurational disorder as comparing with the binary Se-Te glassy alloys. The substitution of some Te atoms by Sn atoms causes variation in the physical properties of the primary binary compound [23].…”
