PbTe unit cell Lead telluride is a compound of lead and tellurium (PbTe). It crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice.

2018年11月1日 · In p-type PbTe, the strategies of band convergence, band alignment and density of state (DOS) distortion are more effective to achieve high electrical transport properties.

For PbTe, PbSe, and PbS, the phonon properties such as phonon dispersion and phonon density of states DOS are calculated by a direct force-constant method. The electronic-structure calculations are performed to derive the necessary parameters and the effect of spin-orbit interaction SOI is examined. The phonon softening processes due to the vol-

2025年1月8日 · In previous studies on PbTe, wire-to-wire variations in anisotropy indicate poor device control, posing a serious challenge for applications. Here, we achieve reproducible anisotropy in PbTe nanowires through a substantial reduction of disorder.
