Peltier cooling at a In-InP interface

Abstract
The cooling due to the Peltier effect was measured by passing electrical current across the liquid‐solid interface in a vertical liquid‐phase epitaxy system. Application of a steady‐state heat‐transfer analysis yielded values for the Peltier coefficient of InP (NDNA?3×1016 cm−3) between 0.21 and 0.50 V in the 300–600 °C temperature range. The cooling temperatures observed could be effectively used for the growth of InP epitaxial layers.
