We address the occurrence of conduction-band crossover in III-V self-assembled quantum dots solely due to misfit strain. Band structure analysis in terms of standard deformation-potential theory shows that Γ-X crossover can occur in the dot, while bo...

Room temperature photoluminescence is reported from GaInAsSbP pentanary alloys grown by liquid phase epitaxy on GaSb. The epitaxial layers exhibited emission in the midinfrared between 3 and 4 μm. Investigation of the structural and photoluminescence... Read More about Midinfrared photoluminescence and compositional modulation in pentanary GaInAsPSb alloys grown by liquid phase epitaxy.

Importance of aspect ratio over shape in determining the quantization potential of self-assembled zinc-blende III-V quantum dots (2007)
Journal Article
Rybchenko, S. I., Yeap, G., Gupta, R., Itskevich, I. E., & Haywood, S. K. (2007). Importance of aspect ratio over shape in determining the quantization potential of self-assembled zinc-blende III-V quantum dots. Journal of applied physics, 102(1), 013706. https://doi.org/10.1063/1.2752127

We have studied the effect of shape on the strain-modified electron/hole confinement potential in zinc-blende quantum dots (QDs), using standard deformation potential theory and an anisotropic continuum-elasticity approximation. Calculations were per... Read More about Importance of aspect ratio over shape in determining the quantization potential of self-assembled zinc-blende III-V quantum dots.
