Millimeter and Sub-millimeter wave Response of Two-Dimensional Hot Electrons in delta doped PbTe Quantum Well

Millimeter and sub-millimeter wave response of two-dimensional hot electrons in double delta doped GaAs quantum well is studied here incorporating deformation potential acoustic, polar optic, ionized background and remote impurity scatterings in the framework of heated drifted Fermi-Dirac distribution function. The inclusion of delta doping is found to enhance the two-dimensional electron density which in turn improves the ac mobility in the GaAs quantum wells thereby providing scope of getting higher speed devices in future.
