| description |
The temperature dependence of the electron lateral mobility in quantum wells
of the GaAs/InGaAs/GaAs heterostructures with delta-like doping has been studied. Two
types of sample doping – in the quantum well and in the adjacent barrier at a small
distance from the well – were used. In the case of shallow wells, in such structures the
experimental results may be well described by known electron scattering mechanisms
taking into account the shape of real envelope wave functions and band bending due to
non-uniform distribution of the positive and negative space charges along the growth
direction of heterostructure layers. In the case of delta-like doping in the well, a good
agreement between experiment and calculations is achieved, if one takes into account a
contribution to electron transport of the states of the impurity band formed by the deltaimpurity beneath the bottom of the lowest quantum subband. |
