We report an AlGaN channel high electron mobility transistor (HEMT) on a sapphire substrate with a 1000-nm A1xGa1-xN (x = 0-0.18)/GaN composite buffer layer, With a significant improvement of crystal quality, the ...
In this paper, we obtain considerable spin-orbit (SO) parameters in AlxGa1-xN/GaN quantum wells (QWs) with sheet carrier concentration N8 = 120 × 10^11/cm^2. With increasing AI content (x) of the barrier, the S...
