p-n-p δ-doped Quantum Wells in GaAs
We present the effectronic structure and relative mobility of a n-type δ-doped quantum well in GaAs surrounded with potential barriers created by p-type δ-doping. The Thomas-Fermi and the effective mass theory has been applied to obtain an analytical expression for the confining potential, and the effectron spectrum, respectively. The effectron energy levels and the relative mobility have been analyzed as a function of the impurity density in the nand ptype planes as well as the distance between them. We have paid special attention to the relative mobility, obtaining an increase in this by a factor of 2 with respect to a single δ-doped well without barriers. So, the p-n-p δ system can be interesting for applications in high speed and high power devices.
