New mechanism of exciton self-localization in quasi-one-dimensional and quasi-two-dimensional semiconductors
Agranovich V.M., Antonyuk V.P., Mal'shukov A.G.
In quasi-one-dimensional and quasi-two-dimensional systems, the Coulomb attraction between bound electrons and holes in different planes or on different filaments leads to deformation of the lattice and the production of self-localized excitons with large translational mass, even in those cases when the interaction with the lattice of the free carriers is negligibly small.
