The wide bandgap II-VI semiconductors have unique properties which allow the possibility of suppressing the exciton-phonon scattering up to room temperature in quantum well structures designed so that the exciton excitation E1s?2s>h?LO. In particular

We have constructed an instrument, CryoEDM, to measure the neutron electric dipole moment to a precision of 10-28 e cm at the Institut Laue-Langevin. The main characteristic is that it is operating entirely in a cryogenic environment, at temperatures

The excitonic properties of cubic ZnS quantum wells in ZnMgS are studied by reflectivity and magneto-optics. A remarkable improvement in the quality of the samples grown by MBE on Gal? substrates has allowed the observation of heavy and light hole ex

A series of Zn0.93Mn0.07Te/ZnTe multiple-quantum well (MQW) structures of different quantum well widths has been studied at 77 K using the conventional modulation technique of photoreflectivity (PR) with above-bandgap light providing the modulation a

We present magnetoreflectivity results indicating the observation of skyrmions in a two-dimensional hole system. The structure is chosen so that the complex valence-band structure causes a crossing of the lowest two spin-split Landau levels at fields

Polarized photoluminescence spectroscopy studies have been performed on two-dimensional hole systems in GaAs-(Al,Ga)As one-side modulation-doped quantum wells in the integer quantum Hall effect regime. Energy shifts of the photoluminescence are obser

We present a magneto-optical study of biexcitons confined within ZnS quantum wells at fields Lip to 57 T. We have measured the luminescence energy splitting of these excitonic systems and find that the results contrast with the conventional picture o
