Polar Optic Phonon Scattering Limited-Mobility in Narrow Quantum Wells

View through CrossRef
Polar optic phonon scattering and mobility limited by such scattering are discussed for quantum wells with widths ranging between 10 nm and 2 nm. Numerical results are given for the InP/Ga0.47In0.53As/InP system for both the bulk-mode and the confined-mode models. Mobilities are found to be close to those given by the infinite-barrier, parabolic-band, bulk-mode model even when all the refinements of bulk-mode theory are taken into account or the analysis is made by using the confined-mode theory.
