The effect of low Al concentration on the electronic structure and thermoelectric properties of AlxGa1−xN/GaN heterojunctions

Jiaming Qi, Chunyan Song, Hui Min Liao, Ning-Xuan Yang et autres

Abstract The effect of low Al concentrations on the electronic structure and thermoelectric properties of AlxGa1−xN/GaN (x = 0.1250, 0.1875, 0.2500, and 0.3125) heterojunctions was investigated using density functional theory and Boltzmann transport theory. Compared to AlxGa1−xN/GaN heterojunctions with different Al concentrations, …
