Thickness Dependences of Kinetic Properties of Quantum Wires of Pure and Doped Bismuth
Last time a great number of researches is devoted to the investigation of quantum and classical size effects . The problem is stimulated by the possibility to detect new effects having no analogues in bulk crystal and to find new applications. From this point of view the bismuth-type semimetals are of particular interest , For instance, in thin monocryStaline bismuth wires, for the first time, the effect of the magnetic flux quantization on a single connected geometry was revealed at the investigation of longitudinal magnetoresistance. However, the influence of sizes on thermoelectric effects, particularly in thin wires, is studied only in a rather limited number of works. Nowadays this problem draws attention due to discovery of high-temperature superconducting materials with critical temperature Tc = 90-130 K. The solid state depth cooling by the Peltier effect employment is of interest in solving the problem of practical use of HTSC materials.
