ABSTRACT OF THE DISCLOSURE Disclosure is made of a method of rectifying alter- nating current by providing a gradient of the ratio of the mobilities of the electrons and holes in a semiconductor with aid of a temperature gradient in which the temperature gradient and bipolar conductivity are provided by self-heating of the material of the semiconductor by the rectified current, in combination with cooling of a part of the material of the semiconductor, with the value of the exponent of the power (.alpha.) of the temperature (T) dependence of the ratio (b) of the mobilities of the electrons and holes /??T.alpha. / being not less than 0.1. The apparatus for performing the method, in accor- dance with the invention, comprises a semiconductor working element with nonrectifying contacts and a cooler adjoining this working element, with the dimensions of the semiconductor working element being selected to provide, in combination with the cooler within the working current range, non-uniform self- heating by the rectified current, with the gradient of the ratio of the mobilities of electrons and holes Image being not less than 0.2 cm-1, and bipolar conductivity of said working element.
