Abstract

The Seebeck coeeficients of AlInN alloys, grown by metalorganic vapor phase epitaxy, with In-contents (x) from 0.38 up to 21.34, were characterized and analyzed from room temperature (T 300 K) up to high temperature (T = 382 K). The Seebeck coefficients of the n-type AlInN alloys show significant enhancement at higher temperature up to 382 K, in comparison to those measured at room temperature. Large Seebeck coefficients (602.0- 1233.2 μ V/K) were obtained for the lattice-matched Al_0.83In_0.17N alloy (n = 5.1 × 10¹⁸ cm^-3) from T = 300 K up to T 382 K. The improvement of Seebeck coefficients for the n-type AlInN alloys will lead to ∼1.5-4 times improvement of the thermopower at higher temperatures.
