Abstract
In a process for vapour coating a semiconductor thermo-electric member, e.g. of Bi2 Te3, the member is maintained at an elevated temperature such as 300-400 DEG C. (50-100 DEG C. lower for a sintered member) during the application of an adhesion layer of e.g. Cr or Mn, and a solderable layer, of, e.g. Cu, is then applied, the transition between the adhesion and the soldering layers being continuous. The vapour coating is carried out in a rarified reducing atmosphere, e.g. in hydrogen, at a pressure of about 5.10-4 mm. Hg.
