Electron-hole many-body correlation effects lead to novel functions of low dimensional field effect devices. In this research project, we have clarified many-body correlation effects by spectroscopic investigations, in particular, by separating the disorder effects in low electron density regime. We have observed emissions from fractionally charged quasiexcitons, which are composite particles with non-integral total charge. Moreover, we have developed a novel spectroscopic measurement method utilizing a near-field scanning optical microscope, and have succeeded in investigating dynamic correlations of non-equilibrium carriers.
