Multiparticle exciton complexes in semiconductors with a large exciton binding energy (ZnO)
Litovchenko V.G. , Babentsov V.N. , Korbutyak D.V. , Ivaniichuk M.T.
A series of lines is observed at high excitation levels in the low-temperature luminescence spectra of ZnO, which are due to formation of polyexcitonic complexes. Formation of a bound electron-hole liquid based on these complexes is shown.
