The interacting electron-hole system is investigated in the framework of non-equilibrium Green's functions. Using the Bethe-Salpeter equation in the ladder approximation we derive a set of equations for the polarization of the interacting electron and hole ...
In this letter the liquid phase epitaxial growth of In0.71Ga0.29As0.68P0.32 (lambda(g) = 1.32 mum) single quantum well structures lattice matched to (001) InP substrates is reported. The electrical and optical confinement was formed either by InP or In0.88 ...
We investigated the optical properties of excitons in quasi-one-dimensional semiconductor quantum structures by photoluminescence and photoluminescence excitation: High-quality GaAs/AlxGa1-xAs heterostructures were grown using low-pressure organometallic c ...
A review with 156 refs. on interfacial electron transfer reactions in colloidal semiconductor solns. and thin films and their application for solar light energy conversion and photocatalytic water purifn. Some of the topics discussed include; optical and e ...
The modification of turbulence in the edge plasma of the DIII-D tokamak at the transition from the low to the high mode of confinement is investigated with a phase-contrast imaging diagnostic. The amplitude and radial correlation length of the turbulence i ...
A theoretical and experimental study of the exciton in ultra-narrow quantum wells (QWs) is performed. A crossover from strong (separate localization of electron and hole levels) to weak confinement (with localization of excitonic center of mass) is predict ...
By means of Raman and photoluminescence measurements we have studied the effect of strain and confinement on the optical phonon spectrum of single InAs quantum wells. The frequency region of longitudinal optical phonons confined in both the InAs well and I ...
