A. Yu. Leiderman, A. S. Saidov, and A. B. Karshiev, Thermoelectric Effect in the Graded Band Gap Si1 – xGex (0.2 ≤ x ≤ 1), Si1 – xGex (0.5 ≤ x ≤ 1) Solid Solutions Dependent on the Gap Difference
The thermoelectric effect, i.e., appearance of thermally stimulated current and voltage during uniform heating in a temperature range from 30 to 250°C, is studied. It is shown that greatest values of the current and voltage appear when maximum band gap difference is observed.
