As-doped SnSe single crystals: Ambivalent doping and interaction with intrinsic defects

Autor: V. Kucek, Anna Krejčová, Vaclav Holy, K. Cermak Sraitrova, J. Cizek, J. Kašparová, Jiří Navrátil, Cestmir Drasar, T. Plecháček

Publikováno v: Physical Review B. 103

We performed ambivalent doping study on single crystals of two sets, SnSe1-xAsx and Sn1-xAsxSe, with the aim to explore the interaction of doping species with intrinsic defects. We found that As atoms substitute preferentially for Se atoms in both se

Autor: P. Ruleova, Cestmir Drasar, Milan Vlček, J. Kašparová, T. Plecháček, Petr Lostak, Ludvík Beneš

Publikováno v: Journal of Electronic Materials. 47:1459-1466

Ceramic samples with the composition Bi2−x Ge x O2Se1.01 (x = 0, 0.05, 0.075, and 0.1) were synthesized by solid-state reaction and compacted using a hot-pressing technique. The prepared materials were characterized by x-ray diffraction analysis, e
