Hall electrical properties measured by the van der Pauw method and low-temperature photoluminescence (77 K PL) spectra of pseudomorphic GaAs/InyGa1-yAs/AlGaAs modulation-doped field-effect transistor-type heterostructures grown by molecular-beam epitaxy we ...
A Hall mobility as high as 176,200 cm2V-1s-1 at 77 K with N(d)-N(a) = 1.3 x 10(14) cm-3 has been obtained by adjusting the substrate and the phosphine cracker temperatures. The 2 K photoluminescence spectra show finely resolved excitonic transitions for la ...
We report on the realization of InGaAs-lnGaAsP separate confinement heterostructure multiple quantum well lasers grown by chemical beam epitaxy. We discuss key growth parameters and characterization by secondary-ion mass spectroscopy, transmission electron ...
