Publikováno v: Solid State Phenomena. 227:71-74

The corrosion behaviour of AM60 magnesium alloy containing 1.88 wt.% Cd in 0.1 M NaCl solution was investigated by weight loss and hydrogen evolution measurements. The microstructure was evaluated using EPMA. Cd was observed to have an even distribut

The growth of GaAs and InAs dots on etched mesas: The effect of substrate temperature on mesa profile and surface morphology on dot distribution

Autor: Stephen Bremner, Paola Atkinson, M. E. Ikpi, David A. Ritchie

Publikováno v: Journal of Crystal Growth. 311:3911-3917

The molecular beam epitaxy (MBE) growth of GaAs and InAs quantum dots on etched mesas has been studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The [0 1 1]-oriented mesas are etched into (1 0 0) GaAs substrates, exp

Distribution of self-assembled InAs dots on patterned GaAs (100) substrates

Autor: M. E. Ikpi, Paola Atkinson, Stephen Bremner, David A. Ritchie

Publikováno v: Journal of Crystal Growth. 278:113-118

We have used pre-growth patterning of a (100) GaAs substrate into mesas to modify the nucleation of InAs quantum dots (QDs) grown by molecular beam epitaxy. The distribution of InAs quantum dots has been assessed using scanning electron microscopy (S
