Excitons and deexcitons in a neutral 2D magnetoplasma with an integer filling of Landau levels: Experiment and theory
Butov L.V., Kulakovskii V.D., Rashba E.I.
A magnetooptic method has been used to study the excitation of a dense, neutral, low-temperature electron-hole magnetoplasma in InGaAs/InP quantum wells with an integer filling of Landau levels. It is demonstrated that stable excitons and deexcitons exist at the Fermi level.
