Interference states of optical excitons. Observation of additional waves
Kiselev V.A., Razbirin B.S., Ural'tsev I.N.
We consider size quantization of optical excitons in ultrathin crystals. It becomes manifest in a special structure of the optical spectrum of the exciton. We observed the interference between the additional waves, which was predicted by Brodin and Pekar [1].
