We have studied the effect of growth interruptions on 2-monolayers-thick InAs/InP strained quantum wells (QW) grown by chemical beam epitaxy. The main feature is the formation of up to 8-monolayers-thick InAs islands during As2 annealing of the QW. Their f ...
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 the growth behaviour of InP, InGaAs and InGaAsP on non-planar InP substrates where ridges were formed with (111)A, (211)A, (111)B and (551BAR) sidewall planes. All three materials grow uniformly on the whole patterned surface with (111)A and (211 ...
Photoluminescence (PL), reflectivity and thermally-detected optical absorption (TDOA) experiments have been carried out, at liquid helium temperatures, On In0.35Ga0.65As/GaAs quantum wells (QWs) with different thicknesses of 4, 6, 8 and 10 monolayers (MLs) ...
