Thermoelectric PbTe-CdTe bulk nanocomposite
M. Szot, K. Dybko, A. Mycielski +4
The preparation method of thermoelectric PbTe-CdTe semiconductor nanocomposite in the form of a bulk material doped with Bi, I or Na, intended for production the mid-temperature th…
Magnetic Constitution of Topologically Trivial Thermoelectric PbTe:Cr
Katarzyna Gas, Aleksandra Krolicka, Krzysztof Dybko +4
In this paper we report on detailed temperature and magnetic field dependence of m agnetization of IV-VI semiconductor PbTe doped with mixed valence transition metal Cr.…
Electron-phonon coupling and a resonant-like optical observation of a band inversion in topological crystalline insulator PbSnSe
Mariusz Woźny, Wojciech Szuszkiewicz, Mateusz Dyksik +5
The optical reflectivity of PbSnSe and PbSnSe solid solutions was measured in the THz spectral region energetically corresponding to bulk opti…
Two-valence band electron and heat transport in monocrystalline PbTe-CdTe solid solutions with high Cd content
M. Szot, P. Pfeffer, K. Dybko +10
High quality p-type PbTe-CdTe monocrystalline alloys containing up to 10 at. of Cd are obtained by self-selecting vapor transport method. Mid infrared photoluminescence experim…
Defect-free SnTe topological crystalline insulator nanowires grown by molecular beam epitaxy on graphene
J. Sadowski, P. Dziawa, A. Kaleta +4
SnTe topological crystalline insulator nanowires have been grown by molecular beam epitaxy on graphene/SiC substrates. The nanowires have cubic rock-salt structure, they grow along…
Alloy broadening of the transition to the non-trivial topological phase of Pb_{1-x}Sn_{x}Te
A. Lusakowski, P. Boguslawski, T. Story
Transition between the topologically trivial and non-trivial phase of Pb_{1-x}Sn_{x}Te alloy is driven by the increasing content of Sn, or by the hydrostatic pressure for $x<0.…
