The simulation of 2DEG in AlzGa1-zN/GaN hetero junction quantum well
In this paper, we take the effect of Al composition in AlxGa1-xN, doped concentration, temperature and passive layer on the AlxGa1-xN/GaN heterojunction quantum well into account. The calculated results of AMPS-1D software show that the effect of different Al composition on the depth of quantum well is slight. On the other hand, the effect of different doped concentration in AlxGa1-xN is obvious. When the doped concentration of GaN is fixed and at the same time we change the one of AlxGa1-xN from 1017 -1021 cm-3.We find that the depth of quantum well and the doped concentration of AlxGa1-xN is positive correlation. Finally, the depth of well is deeper when the temperature is higher.
