Polar Optical Phonon Modes and Fröhlich Electron-Phonon Interaction Hamiltonians in Coaxial Cylindrical Quantum Cables
Optical Phonon Modes Coaxial Cylindrical Quantum Cables
2010/4/12
By using the dielectric continuum approximation, the polar optical phonon modes of coaxial cylindrical quantum cables with arbitrary layer-number were studied. In order to describe the vibrating of th...
The Extended Hybrid Model For Optical Phonon Confinement
Hybrid Model Optical Phonon Confinement
2010/4/16
The theory of optical phonons and their confinement in heterostructures is reviewed with analogies made to the theory of acoustic phonons. The dielectric continuum (DC) model is obtained when bulk dis...
