On the AC-conductivity mechanism in nano-crystalline Se 79−x Te 15 In 6 Pb x ( x = 0, 1, 2, 4, 6, 8 and 10) alloys

On the structural and thermophysical study of Pb-doped Se-Te-In nanochalcogenide alloys

“…This in turn produces thermally more stable glassy alloys by reducing aging effect and enhancing glass forming ability. Pb doping prominently makes an impact on physical, structural, electronic, optical, and thermal properties of host material [2,17]. Our preceding research on ternary Se-Te-In composition signifies that In = 6 at.…”

“…In scientific research, the nanostructure configurations are gradually becoming promising materials owing to basic research point of view as well as for their inimitable features as distinctive optical properties, exclusive electronic properties, an enormous surface-to-volume ratio, etc., as contrasted to bulk systems [1,2]. Moreover, the nanostructure synthesis has been analyzed for several materials in consequence of advancement in the characterization and visualization techniques.…”

“…The metal-containing nanocrystalline materials are well-known promising materials owing to their some unusual properties, including anomalous order of band gaps, high carrier mobility, exclusive chemical durability, high dielectric constant, extended infrared (IR) transparency, high reflection index, low phonon energy, high photo sensitivity, high thermal stability, and special nonlinear optical properties [2,[7][8][9]. These fascinating and incomparable properties of lead nanostructured semiconductors have inculcated great interest in the fundamental studies of these materials.…”

“…These materials are useful in optical memory switching rectifiers and photocells due to observation of reversible transformation [13]. But these Se-based alloys found to be thermally unstable and have limited reversibility for technological applications [2]. However, the insertion of trace elements is one of the most efficient techniques for developing new alloys with improved properties.…”

“…The fundamental interest in multicomponent quaternary chalcogenide alloys has been revived due to the observation of quick reversible laser-induced crystalline to amorphous and amorphous to crystalline phase transitions. Quaternary chalcogenide alloys act as considerable source of tuneable emission in IR wavelength region [2,20,21]. In device fabrication, the lattice perfection and the optical gap of the material plays an important role which can be modified by the insertion of the doping element like Pb.…”
