Direct evidence of enhanced Ga interdiffusion in InAs vertically aligned free-standing nanowires
J. C. Gonz'alez, A. Malachias, J. C. de Sousa +3
We present direct evidence of enhanced Ga interdiffusion in InAs free-standing nanowires grown at moderate temperatures by molecular beam epitaxy on GaAs (111)B. Scanning electron…
Strain selectivity of SiGe wet chemical etchants
M. Stoffel, A. Malachias, T. Merdzhanova +6
We investigate the effect of strain on the etching rate of two SiGe wet etchants, namely NH4OH:H2O2 and H2O2. For both etchants, we found that there is no appreciable strain select…
Atomic ordering in self-assembled Ge:Si(001) islands observed by X-ray scattering
A. Malachias, T. U. Schulli, G. Medeiros-Ribeiro +4
X-ray diffuse scattering in the vicinity of a basis-forbidden (200) Bragg reflection was measured for a sample with uncapped self-assembled Ge islands epitaxially grown on Si(001).…
