We have carried out a theoretical calculation of the differential cross section for the electron Raman scattering process associated with the surface optical phonon modes in a semiconductor quantum disc.electron states are considered to be confined within a quantum disc with infinite potential barriers.The optical phonon modes we have adopted are the slab phonon modes by taking into consideration the Frohlich interaction between an electron and a phonon.The selection rules for the Raman process are given.Numerical results and a discussion are also presented for various radii and thicknesses of the disc,and different incident radiation energies. 相似文献

CONCISE POLARON MODEL TO THE CALCULATION OF BINDING ENERGY IN SOME STRONG-AND WEAK-COUPLING POLAR CRYSTALS 下载免费PDF全文
A new concise polaron model is proposed to study the ground state of polarons in some strong-and weak-coupling polar crystals. The ground state energy and binding energy of these materials are calculated numerically by iteration method. Results are in close agreement with the experimental data. 相似文献
