Using a set of glass-insulated Bi–0.02 at %Sn wires with diameters varying in a range of 0.2–1 μm prepared by liquid-phase casting by the Ulitovsky method, a complex of measurements of the temperature dependences of resistivity ρ(T), thermoelec

Thermoelectric-energy conversion based on a single element made of an anisotropic material is considered. In such materials, the heat flux generates a transverse electric field. We fabricate an experimental heat-flux sensor (HFS) sample consisting of

Here we investigated the field emission effect in nanoconstrictions made on the basis of the microwire in glass insulation. Glass-coated single-crystal microwires of Bi and Bi-Sb were fabricated by the Ulitovsky method; then, using the technique of l

The temperature dependencies of thermal conductivity χ(Т), electrical conductivity σ(Т), and thermopower α(Т) in foils of Bi1–xSbx alloys in the semimetal and semiconductor states, in a temperature range of 4.2–300 K, were experimentally st

Thermoelectric heat conversion based on the Seebeck and Peltier effects generated at the junction between two materials of type-n and type-p is well known. Here, we present a demonstration of an unconventional thermoelectric energy conversion that is

When electrons are confined in two-dimensional materials, quantum-mechanical transport phenomena and high mobility can be observed. Few demonstrations of these behaviours in surface spin-orbit bands exist. Here, we report the observation of quantized

The features associated with the manifestation of Lifshitz electron topological transitions (ETT) in glass-insulated bismuth wires upon qualitative changes to the topology of the Fermi surface are investigated. The variation of the energy spectrum pa

Recent efforts to detect and manipulate Majorana fermions in solid state devices have employed topological insulator (TI) nanowires proximity coupled to superconducting (SC) leads. This combination holds some promises for the fundamental physics and
