The Aharonov-Bohm effect (AB) exists in cylindrical wires as the magnetoresistance (MR) oscillations with a period ΔB that is proportional to Φ 0 /S, where Φ 0 = h/e is the flux quantum and S is the wire cross section. The AB-type longitudinal MR

Bulk bismuth is an efficient thermoelectric material. Assuming intrinsic conditions, the theory of quantum confinement of bismuth nanowires by Hicks and Dresselhaus predicts a semimetal-to-semiconductor transformation for critical diameters of around

The temperature dependence (4.2–300 K) of the thermopower of thin Bi wires was investigated. The cylindrical Bi crystals ranging in size from 0.19 to 3 µm were prepared by high-frequency liquid-phase casting in a glass capillary. The nanowires are

Thermoelectric and magneto-thermoelectric properties of quantum wires of bismuth doped with Te were investigated at electron topological transitions (ETT) induced by stretch in the temperature interval 4.2-300 K and magnetic fields up to 14T. Single

The λ-modulated exciton reflection spectra of Tl3AsS3 crystals are investigated at 8 and 77 K, in which the ground (n=1) and excited (n=2, 3) exciton states are revealed. Taking into account the spatial dispersion, the shapes of λ-modulated reflect

We have shown that the Fermi energy dependence on temperature in semimetals keeps its well-known form, similar to that of semiconductors, down to T = 0. In the nearest vicinity of T = 0 this dependence is significantly changed, and the Fermi level is
