Epitaxial Growth of Optoelectronically Active Ga(As)Sb Quantum Dots on Al-Rich AlGaAs with GaAs Capsule Layers

<div>Atomic force micrographs of (a) active Ga(As)Sb QDs on GaAs and (b) nonactive QD-like objects grown from Ga(As)Sb on Al<sub>0.5</sub>Ga<sub>0.5</sub>As. Be aware of the different scale in the height dimension as opposed to both lateral dimensions along the growth front.</div>
