Here, we report the investigation of the anomalous Hall effect in the magnetically doped topological insulator (V,Bi,Sb)_{2}Te_{3}. We find it contains two contributions of opposite sign. Both components are found to depend differently on carrier den

Infrared reflection spectra of thin (∼60 nm) Pb1−x Sn x Te (x = 0.25, 0.53, 0.59) films grown by molecular beam epitaxy on GaAs/CdTe hybrid substrates have been measured at frequencies from 20 to 5500 cm−1 and temperatures from 5 to 300 K. The

Reflectance spectra of thin Pb1 –xSnxTe films (~60 nm) with x = 0.25, 0.53, and 0.59, grown by MBE on hybrid GaAs/CdTe substrates, are measured in the frequency range of 20–5500 cm–1 and the temperature range of 5–300 K. The temperature depen

Measurements of magnetotransport in SnTe/PbTe heterojunctions grown by the MBE technique on (001) undoped CdTe substrates were performed. At low magnetic fields, quantum corrections to conductivity were observed that may be attributed to the presence

Achieving metrological precision of quantum anomalous Hall resistance quantization at zero magnetic field so far remains limited to temperatures of the order of 20 mK, while the Curie temperature in the involved material is as high as 20 K. The reaso

In recent attempts to observe axion electrodynamics, much effort has focused on trilayer heterostructures of magnetic topological insulators, and in particular on the examination of a so-called zero Hall plateau, which has misguidedly been overstated

Thin epitaxial Pb1−xCdxSe films with cadmium content x ≤ 0.36 have been grown by molecular beam epitaxy (MBE) on highly resistive, lattice matched (0 0 1) ZnTe/GaAs hybrid substrates. The High Resolution X-ray Diffraction (HRXRD) indicates that t

We study the crystal structure-mismatched, quantum dot-like (QD) composite metamaterial based on rock-salt narrow gap PbTe and zinc-blende wide gap CdTe. In the case of PbTe/CdTe QDs the quantum effects are observed for dots with dimensions of the or
