The magnetopolaron wave function and energy for resonantly coupled electronic and vibrational excitations in a quantum well are derived and used to evaluate the efficiency of Raman scattering by two LO phonons. A strong increase of the scattering intensity along with the splitting of Raman peaks is predicted in the magnetopolaron regime.
ErrataErratum: Two-dimensional disordered electronic systems in a strong magnetic field [Phys. Rev. B 47, 2089 (1993 Y. Avishai and R. M. Redhe8erWe have traced an error in theorem 1, and note below that it is in fact possible to (1) require weaker conditions and (2) find a more elegant proof. Thus, the conclusions drawn in the original paper are affected in the sense that they now exist under weaker conditions. We can now demonstrate the following proposition.Let Iz J be a set of nonzero complex numbers arranged in increasing order of~z , i and let lim""r N(r}=a )0, where N(r) is the number of z. in ized & r. Let I wj J be another sequence of nonzero complex numbers close to Iz I in the sense that m 1 1 lim =1, g z -2 m~oo Zm J Resonant Raman scattering by one LO phonon via Frohlich interaction was studied for quantum wells in the magnetopolaron range. The contribution of two diagrams in Figs. 1(a) and 1(b) (referred to as A and B below) of the original paper to the scattering amplitude was calculated taking into account the renormalization of the electron Green function
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
