Luminescence from Miniband States in Heavily Doped Superlattices
We have studied doped superlattices of GaAs/AlGaAs composition. When the doping atoms are introduced into the barriers surrounding the superlattice, as well as to the inner ones, but with half of the concentration, the photoluminescence due to interband transitions from extended superlattice states is detected. This is demonstrated by a study of the sample’s photoluminescence in a magnetic fiel...
متن کاملBright luminescence from erbium doped nc-Si=SiO2 superlattices
Optical properties of Er doped Si=SiO2 superlattices and SiO=SiO2 superlattices are compared. In the case of Si=SiO2 superlattices with Si layers thicknesses between 2 and 19 nm polycrystalline like Si layers are observed after annealing. The samples show a very weak defect related red room temperature luminescence. No significant enhancement of the Er luminescence could be shown. The SiO=SiO2 ...
متن کاملMiniband transport and oscillations in semiconductor superlattices
We present and analyse solutions of a recent derivation of a drift-diffusion model of miniband transport in strongly coupled superlattices. The model is obtained from a single-miniband Boltzmann–Poisson transport equation with a BGK (Bhatnagar–Gross–Krook) collision term by means of a consistent Chapman–Enskog expansion. The reduced drift-diffusion equation is solved numerically and travelling ...
متن کاملMiniband-related 1.4–1.8 μm luminescence of Ge/Si quantum dot superlattices
The luminescence properties of highly strained, Sb-doped Ge/Si multi-layer heterostructures with incorporated Ge quantum dots (QDs) are studied. Calculations of the electronic band structure and luminescence measurements prove the existence of an electron miniband within the columns of the QDs. Miniband formation results in a conversion of the indirect to a quasi-direct excitons takes place. Th...
متن کاملTime-resolved luminescence studies of heavily nitrogen doped ZnSe
Time-resolved luminescence data from heavily nitrogen doped ZnSe ~total N concentration exceeding mid-10/cm) is presented. The luminescence exhibited a decay time and a rise time which increased with decreasing energy of observation. Furthermore, both the decay times and rise times decreased with increasing temperature. These observations are consistent with the following model: ~i! a band of s...
