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

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

متن کاملEffects of Double Delta Doping on Millimeter and Sub-millimeter Wave Response of Two-Dimensional Hot Electrons in GaAs Nanostructures
Carrier mobility has become the most important characteristic of high speed low dimensional devices. Due to development of very fast switching semiconductor devices, speed of computer and communication equipment has been increasing day by day and will continue to do so in future. As the response of any device depends on the carrier motion within the devices, extensive studies of carrier mobilit...

The potentiality of millimter-wave (mm-wave) double-drift region (DDR) impact avalanche transit time (IMPATT) diodes based on a wide bandgap (WBG) semiconductor material, Gallium Phosphide (GaP) has been explored in this paper. A non-sinusoidal voltage excited (NSVE) large-signal simulation method has been used to study the DC and high frequency characteristics of DDR GaP IMPATTs dsigned to ope...
متن کاملQuantum dot superlattice thermoelectric materials and devices.
PbSeTe-based quantum dot superlattice structures grown by molecular beam epitaxy have been investigated for applications in thermoelectrics. We demonstrate improved cooling values relative to the conventional bulk (Bi,Sb)2(Se,Te)3 thermoelectric materials using a n-type film in a one-leg thermoelectric device test setup, which cooled the cold junction 43.7 K below the room temperature hot junct...
