| Abstract: | Electron Raman scattering (ERS) is investigated in a
free-standing semiconductor quantum wire of cylindrical geometry for
two classes of materials CdS and GaAs. The differential cross
section (DCS) involved in this process is calculated as a function
of a scattering frequency and the radius of the cylinder. Electron
states are considered to be confined within a free-standing quantum
wire (FSW). Single parabolic conduction and valence bands are
assumed. The selection rules are studied. Singularities in the
spectra are found and interpreted for various radii of the cylinder. |
