Deep, free, and bound excitons and biexcitons in GaSe and their collective interaction
Solomonov Yu.F., Subashiev V.K.
The binding of deep excitons in a molecule and the interaction of these formations with each other and with carriers as well as with deep, exciton-impurity complexes (EIC) were observed for the first time. The parameters of the states and of the processes were determined.
