Abstract
The scattering intensity (SI) for an electron resonant Raman scattering (ERRS) process associated with bulk longitudinal optical (LO) phonon modes and surface optical (SO) phonon modes is calculated separately for T=0K in a free-standing semiconductor quantum wire of cylindrical geometry. We consider the Fröhlich interaction to illustrate the theory for a AlAs system. Electron states are considered to be confined within a free-standing quantum wire (FSW). We also assume single parabolic conduction and valence bands. The selection rules are studied. Numerical results and a discussion are also presented for various cylindrical radii.
