We report electroluminescence experiments on HgTe/Cd 0.7 Hg 0.3 Te quantum wells with inverted band structure in strong lateral electric fields. The electroluminescence is found to appear above a critical bias. Spectral measurements show emission pea

The conductivity of single layer and bilayer graphene ribbons 0.5–4 μm in width fabricated by oxygen plasma etching is studied experimentally. The dependence of the electron concentration in graphene on the ribbon width is revealed. This effect is

The longitudinal and Hall components of the resistivity tensor are measured in structures with multiple HgTe layers 16 nm thick in magnetic fields to 12 T at temperatures from 1.5 to 300 K. The slope of the magnetic-field dependence of the Hall resis

We report terahertz photoconductivity in epitaxial graphene devices patterned in a meander shape with the length up to a few centimeters and the width of few tens of microns. The photoresponse signal was measured at wavelengths of 280, 148 and 90 mic

The terahertz photoconductivity of epitaxial graphene grown on a SiC substrate is studied in magnetic fields. Under a magnetic field applied perpendicular to the sample’s plane, a strong increase in the photoconductivity signal was detected due to

Injection-induced terahertz electroluminescence from silicon p +–n structures is observed at helium temperatures. Structures fabricated by the diffusion of boron into a phosphorus-doped n-Si substrate are studied. Relatively narrow luminescence lin

Recently Ma et al. (Nature Nanotech. 14, 145, 2019) reported an intrinsic photocurrent in graphene, which occurs as the authors believe “in a different parameter regime from all the previously observed photothermoelectric or photovoltaic photocurre

We observe a dc electric current in response to terahertz radiation in lateral inter-digitated double-comb graphene p-n junctions. The junctions were fabricated by selective ultraviolet irradiation inducing p-type doping in intrinsic n-type epitaxial
