Many body effects and internal transitions of confined excitons in GaAs and CdTe quantum wells
Autor: Dmitri R. Yakovlev, C. J. Meining, Madalina Furis, H. A. Nickel, Alexander B. Dzyubenko, B. D. McCombe, Athos Petrou
Publikováno v: Solid State Communications. 127:821-827
Many body effects contribute significantly to the energy states of electron–hole pairs confined in quantum wells in the presence of excess electrons. We present results of optically detected resonance spectroscopy of the internal transitions of pho

Autor: Andreas Waag, Dmitri R. Yakovlev, Scott A. Crooker, G. V. Astakhov, W. Ossau, H. A. Nickel, B. D. McCombe, C.J Meinig
Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 12:512-515
Properties of a two-dimensional electron gas with a density of 5×10 11 cm −2 in a ZnSe/(Zn,Be,Mg)Se quantum well structure have been investigated by means of polarized magneto-luminescence in fields up to 47 T and by an optically detected resonanc

Autor: T. Yeo, Alexander B. Dzyubenko, H. A. Nickel, Athos Petrou, B. D. McCombe
Publikováno v: physica status solidi (b). 227:365-379
The states of charged magnetoexcitons in two-dimensional systems are considered. Exact optical selection rules for intra- and inter-band processes are discussed. The effect of excess electrons on internal transitions of negatively charged excitons X
