Quasi-one-dimensional density of states in a single quantum ring
Generally confinement size is considered to determine the dimensionality of nanostructures. While the exciton Bohr radius is used as a criterion to define either weak or strong confinement in optical experiments, the binding energy of confined excitons is difficult to measure experimentally. One alternative is to use the temperature dependence of the radiative recombination time, which has been...
متن کاملPhotoluminescence from electron-hole plasmas confined in Si/Si1-xGex/Si quantum wells
We report the first observation of photoluminescence from electron-hole plasmas in Si/S&,sGe&Si quantum wells. While at liquid helium temperature, luminescence due to shallow bound excitons is observed. At 77 K electron-hole plasma (EHP) luminescence dominates the spectra over a wide range of pump powers. Convolution of the occupied electron and hole densities of states gives an excellent fit t...
متن کاملIntraband transitions in magnetoexcitons in coupled double quantum wells
A theory of far-infrared ~FIR! magneto-optical intraband s→p transitions of direct and indirect excitons in semiconductor coupled double quantum wells has been developed. The case of symmetric strained InxGa12xAs/GaAs quantum wells with nondegenerate valence band in the regime of both narrow and wide barriers has been analyzed. The energies and dipole matrix elements of transitions between the ...
متن کاملDynamical transport of photoexcited carriers between shallow and deep quantum wells embedded in a GaAs/AlAs superlattice
Temperature dependence of the emission properties in a novel composite quantum-well-structure consisting of wide and narrow GaAs quantum wells (QWs) embedded in a GaAs/AlAs short-period superlattice (SPS) has been studied by steady-state and time-resolved photoluminescence (PL) measurements. At low temperature (~20 K), distinct PL peaks originating from the QWs and SPS are observed. When temper...
متن کاملCoherence length of cold exciton gases in coupled quantum wells.
A Mach-Zehnder interferometer with spatial and spectral resolution was used to probe spontaneous coherence in cold exciton gases, which are implemented experimentally in the ring of indirect excitons in coupled quantum wells. A strong enhancement of the exciton coherence length is observed at temperatures below a few Kelvin. The increase of the coherence length is correlated with the macroscopi...
