Abstract. The properties (electric, galvanomagnetic, tensoelectric) of the whisker crystals such as Si-Ge and Te-Se solid solutions, Te, 111-V compounds (GaAs, Gap, GaAsP) have been studied in a wide temperature range from 4.2 (for a number of cases from 0.4) to 300 K. The set of thermal, magnetic and mechanical sensors based on these materials has been developed. The sensors are favorably characterized by their miniature dimensions, high speed operation and improved metrological performance.
