“…In this case the longitudinal and transverse heat fluxes are mutually transformed. As was shown in [14], this flux transformation can give rise to a super-fast motion of the temperature±electric domains. The temperature±current filaments can also move with a super-fast velocity due to the above-mentioned flux transformation.…”

“…According to [14], for the investigation of the thermal±electric instability of anisotropic metals the thermoelectric effect can be neglected in the thermal conductivity equation (1). The reason is that the thermoelectric coefficient a is small (it is proportional to kTae F ( 1, where k is the Boltzmann constant and e F is the Fermi energy) while mixing of the longitudinal and transverse heat fluxes in anisotropic metals results in an effective thermoelectric coefficient that greatly exceeds the conventional one a.…”

“…In analogy to [14] the anisotropy in the thermal conductivity of a metal was shown to modify the TED dynamic radically, leading to an increase of the TED velocity by several orders of magnitude up to the values of the order of Fermi velocities v F % 10 8 cm/s. In order to realize this super-fast motion of TED in normal metals, a specially prepared sample placed in a strong magnetic field was proposed in [14]. In Section 4 the temperature±current filaments are also shown to move at super-high velocities due to the anisotropy of the thermal conductivity of the metal in a strong magnetic field.…”

The temperature±current filament instability in a thin plate of an anisotropic compensated metal under the Joule heating in a strong magnetic field is theoretically investigated. An effective thermoconductivity equation for the temperature of an anisotropic metal averaged with respect to the plate thickness is derived. The metal anisotropy and finite thickness of the plate are shown to modify qualitatively the dynamics of the temperature±current filaments. In the kink regions of the temperature±current filaments eddy currents are shown to arise that can result in a new physical mechanism of a super-fast motion of the filaments at velocities up to the Fermi velocity, 10 8 cm/s.

“…This means that the superconductive inclusions can act as effective scattering centers. An increase in the resistance of a semiconductor-normal (S-N) boundary has been predicted by Kadigrobov [3]. The effect is due to scattering of a part of the electrons ("the gliding electrons") by an S-N boundary.…”

We report on the first experimental observations of an anomalous increase in the resistance of a semiconductor-superconductor contact in the vicinity of the critical temperature T. The effect is found in lead-doped InSb thin films having inclusions of lead of 1-3µm in diameter: The observed effect can be a model that explains similar resistance increase observed sometimes in the high 7', superconductors. PACS numbers: 72.2 0.My, 74.50.+r Sample preparation and characteristicsLead-doped InSb thin films, 2-3 μm thick, were obtained by the coevaporation of InSb and lead from separate sources on ceramic substrates. The film preparation method was essentially the same as that for tin-doped InSb films [1]. The lead content in the films was varied by a change of the Pb-evaporation-source temperature between 950 K and 1250 K. Several films were obtained in one evaporation process. A part of the films from each evaporation un was regrown from the melt by a microzone-melting procedure [1].The electrical properties of the films were investigated with the Hall effect measurements. The morphology and chemical composition of the films were studied with optical microscope observations and selective etchings accompanied with chemical analysis. Further detailed studies of the morphology and chemical composition were carried out with a scanning electron microscope and X-ray microanalyser [1]. The investigation results can be summarized as follows. With-*This paper was presented at
