Effect of composition on transport properties of Ge10AsxTe902x chalcogenide system
Chalcogenide bulk alloys of Ge10AsxTe90-x(x=20, 25, 30, 35, 40, 45 and 55) system were prepared by the conventional melt quench-technique. The dc electrical conductivityrand thermoelectric power (TEP) measurements were carried out in the temperature ranges from 83 to 353 K and from 253 to 353 K, respectively. The variations of bothrand TEP with temperature proved n-type semiconducting behavior of these ... إقراء المزيد
