“…Lead chalcogenide (PbS, PbSe, and lead telluride [PbTe]) and their alloys have been the subject of considerable research because of the technological importance of these materials as detectors of infrared radiation and more recently as infrared emitters and solar control coatings [1][2][3]. PbTe semiconductor has been of special interest because of its potential application as a thermoelectric material, infrared detectors, IR filters, and lasers in the 3-30 μm range [4,5].…”

Lead Telluride (PbTe) films of different thickness were prepared onto precleaned glass substrates under the pressure of 2×10 −5 Torr by thermal evaporation. X-ray diffraction technique, scanning electron microscopy, and current-voltage characteristics were used to characterize the films. The structural analysis of the films was carried using X-ray diffractometer. The surface morphology was analyzed by using scanning electron microscope. The dc electrical conduction mechanism in vacuum-evaporated Al/PbTe/Al thin film sandwich system in the thickness range 500-5,000 Å at different temperature (303-483 K) was found to be a modified Poole-Frenkel type. The results of variation of activation energy with applied voltage and thickness are discussed.

“…Lead chalcogenides (PbS, PbSe and PbTe) and their alloys have been the subject of considerable research due to the technological importance of these materials, in crystalline and polycrystalline forms, as detectors of infrared radiation and more recently as infrared emitters and solar control coatings also [4][5][6][7][8]. The physico-chemical properties of lead chalcogenides have much in common: they are isomorphous, have the same type of chemical bonding, can be prepared by similar methods, have similar phase diagrams, and can be doped in a similar manner.…”

“…Lead chalcogenides, e.g. PbS, PbSe and PbTe and their alloys have been the subject of considerable research due to the technological importance of these materials, in crystalline and polycrystalline forms, as detectors of infrared radiation and more recently as infrared emitters and solar control coatings also [8][9][10][11][12]. The study of ternary alloys of selenium-lead is of particular interest because of their applications in the fabrication of infrared detectors, solar cells and other optoelectronic devices.…”
