Microwires with semiconductor and semimetal wires have a number of features compared to massive semiconductor crystals. This is due to the high speed of casting of these microwires and allows 2-3 times to expand the mutual solubility of the components of solid solutions, and also to obtain crystals that are not synthesized at all by conventional methods, which makes it possible to create fundamentally new microconverters on their basis. They have unique properties: linear magneto-resistance in weak fields, high coefficient of thermopower. etc. Due to the micron diameter of the core (up to 0.2 [Jm), commensurate with different characteristic lengths of semiconductor and semimetallic materials, such microwires are unique objects for the study of classical and quantum dimensional effects. Possible applications are galvanomagnetic elements and converters; converters of electrical and non-electrical quantities; thermoelectric converters (thermocouples, micro-refrigerators); infrared and hard radiation detectors; Germanium optical fibers for the transmission of information in the infrared range.

What is a nanowire? Nanowires are small-diameter wires for manufacturing windings of electric micromachines, measuring coils and control devices. Nanowires are obtained from various metals and alloys: conductive, resistive, magnetic, semiconductor, with their simultaneous coating by glass insulation, with a diameter of less than 1 μm, including precious materials (Au, Pt, Ag, etc.). The use of nanowires - non-electric measuring transducers (temperature, pressure, speed, force, mass, etc.); - inductive converters; - transformers, motor windings; - complexes of filamentous nanostructures; - electrodes.
