Abstract In this paper, Pb 1−x In x Te (0.00 ≤ x ≤ 0.20) thin films were epitaxially grown on BaF 2 (111) sub-strate using molecular beam epitaxy (MBE). The results show that when x ≤ 0.06, In atoms act as substitutional doping in PbTe, forming n type cubic Pb 1−x...

A unidirectional solidification experiment by Bridgman method has been performed for the Pb14Bi28.8Te57.2 composition, which lies on the pseudo-binary PbTe–Bi2Te3 system, resulting in the...doi:10.1007/s10853-011-5301-6Teruyuki IkedaMarcus B. Toussaint...
氨基化InAs砷化铟量子点/砷化镓GaAs量子点/PbTe碲化铅量子点(实验供应) 量子点(quantum dot)是在把激子在三个空间方向上束缚住的半导体纳米结构。有时被称为“人造原子”、“超晶格”、“超原子”或“量子点原子”,是20世纪90年代提出来的一个新概念。这种约束可以归结于静电势(由外部的电极,掺杂,应变,杂质产...
The results of EPMA, SEM, and X-ray diffraction (XRD) measurements show that formation of In solid solutions in lead telluride matrix revealed not only in PbTe–InTe cross-section, but in PbTe–In 2Te 3 pseudobinary system also. The results of XRD show that the lattice parameter a PbTe ...
PbTe is a typical intermediate-temperature thermoelectric material, which has undergone extensive developments and achieved excellent high thermoelectric performance. In this perspective we summarized several strategies that were successfully applied in
PbTe-based thin films were deposited by thermal evaporation at temperatures ranging from ambient temperature to 430掳C on different vicinal GaAs (100) substrates and BaF2(111). This materials system is being evaluated as a potential candidate thermoelectric material for a mid-temperature stage in a...

The electronic charge density for PbTe is computed as a function of position in the unit cell and is displayed on two different planes. A rough estimate of the charge about each atom is made. The charge density for the top valence and bottom conduction bands are given for the L point of...
PbTe–polyaniline (PANi) composite nanopowders were in situ fabricated via an interfacial polymerization method at room temperature (~293K). The phase structure, composition, and morphology of the powders were characterized by X-ray powder diffraction, infrared spectroscopy, transmission electron microscopy...
