Abstract
Abstract A thermoelement comprising a monocrystal possessing different electric conduction coefficients along at least two principal crystallographic axes, wherein a thermoelectromotive force appears under the effect of the thermal flux therethrough, and at least one shorting member electrically connecting at least two points on said monocrystal, which lie opposite to each other on the outer surface thereof and in the plane passing through said two principal crystallographic axes, so that the straight line interconnecting these points forms an angle other than 0* and 90* with one of said principal crystallographic axes. Said member is designed to short the thermoelectromotive force component the direction whereof coincides with that of said thermal flux. The thermoelement also comprises leads to tap current from the monocrystal in a direction normal to said straight line interconnecting said two points on the monocrystal and in the plane passing through said two principal crystallographic axes.
