Polarization of recombination radiation of bound multiexciton complexes (BMC) in silicon in a magnetic field
We investigated the polarization of the TO emission lines of multiexciton complexes bound with boron. It was observed that the polarizations of the lines Am with m = 1,2,3 excitons bound to the acceptor differ in magnitude and sign. This result confirms the BMC model, and cannot be explained by other existing models. A model of the BMC state is proposed, in which account is taken of the dependence of the energy on the type of valley states and on the orbit-valley splitting. The degree of polarization of the BMC emission lines calculated within the framework of this model agrees with the experimental results.
