Abstract
The improvement of transport electron mobility μ is theoretically reported through a change in well width w in an asymmetric V-shaped double quantum well (AVDQW) structure. The side barriers are doped with different doping concentrations i.e., N d1 (vary) and N d2 (fixed) towards the substrate and surface respectively which produces asymmetry in the structure. An increase in w enhances μ. The magnitude of μ is decided by the alloy disorder scattering but the trend in the variation of μ as a function of N d1 is mainly decided by the impurity scattering.
