ABSTRACT
Thermoelectric properties of lattice-matched AlInN grown by metal organic chemical vapor deposition were measured and analyzed. The n-type Al0.83In0.17N alloy exhibited thermal conductivity of 4.87 W/(m K) measured by 3ω differential method. The Seebeck coefficient of n-Al0.83In0.17N was measured as -6.012×10-4 V/K by thermal gradient method. The sheet resistivity of n-Al0.83In0.17N was measured by using Van der Pauw method, and the electrical conductivity was measured as 2.38×104/(Ω m). The thermoelectric figure of merit (Z*T) of n-type Al0.83In0.17N was measured as 0.532 at room temperature (T=300 K). The finding indicates lattice-matched AlInN alloy on GaN as excellent material candidate for thermoelectric application.
