Multi-subband electron mobility in AlGaAs parabolic quantum wells
We analyze the enhancement of multisubband electron mobility in delta-doped AlxGa1-xAs parabolic quantum well structures. We show that mobility is considerably enhanced in a parabolic quantum well compared to that in a square quantum well due to shifting of subband electron wave functions towards the centre of the well through the influence of the parabolic structure potential. We analyse the interplay of different scattering mechanisms on subband mobility mediated by intersubband interactions which leads to interesting results.
