A review of experimental results obtained by different techniques is presented on the problem of zinc diffusion. Zinc diffusion was carried out on Si-doped GaAs (n almost-equal-to 10(18) cm-3) and on multiple quantum well (MQW) structures. The samples were ...
The laser-induced luminescence of direct gap semiconductors can be measured with high spatial (1 μm) and temporal (<1 ns) resolution. A profiling technique is described for in-situ measurements during laser processing. It allows the evaluation of tem ...
We use the cathodoluminescence mode of a scanning electron microscope to investigate the depth and lateral dependencies of the electron-hole pairs generation by the electron beam in Al0.4Ga0.6As semiconducting material. A multiquantum well structure acts a ...
A set of parameters for the temperature dependence of the direct band gap of InP has been determined by fitting the excitonic recombination energy in the photoluminescence (PL) spectra between 2 and 250 K. We have used high-quality InP samples grown by che ...
