Heat flow asymmetry on a junction of quartz with graphite

Abstract

The thermal conductivity of a quartz with graphite junction is studied in the temperature range 6 to 95 K. The junction rectification reaches 70% for a temperature difference of 40 K between the thermometers. A quartz junction of the material identical on both sides of the contact, produced for control, does not show the rectification phenomenon. [Russian Text Ignored].
