Self-assembled InAs quantum dot formation on GaAs ring-like nanostructure templates

The evolution of InAs quantum dot (QD) formation is studied on GaAs ring-like nanostructures fabricated by droplet homo-epitaxy. This growth mode, exclusively performed by a hybrid approach of droplet homo-epitaxy and Stransky-Krastanor (S-K) based QD self-assembly, enables one to form new QD morphologies that may find use in optoelectronic applications. Increased deposition of InAs on the GaAs...

Effect of growth interruption on photoluminescence of self-assembled InAs/GaAs quantum dot heterostructures

The effects of growth interruption (GI) on self-assembled InAs/GaAs quantum dot (QD) heterostructures have been presented. Samples with different GI times were grown on GaAs substrate by metal-organic chemical vapour epitaxy. Photoreflectance and temperature dependent photoluminescence (PL) spectra from the samples were measured. It is found that increasing GI time during InAs QDs formation ind...

Exciton Fine-Structure Splitting in Self-Assembled Lateral InAs/GaAs Quantum-Dot Molecular Structures.

Fine-structure splitting (FSS) of excitons in semiconductor nanostructures is a key parameter that has significant implications in photon entanglement and polarization conversion between electron spins and photons, relevant to quantum information technology and spintronics. Here, we investigate exciton FSS in self-organized lateral InAs/GaAs quantum-dot molecular structures (QMSs) including lat...

Thermal Effects and Small Signal Modulation of 1.3-μm InAs/GaAs Self-Assembled Quantum-Dot Lasers

We investigate the influence of thermal effects on the high-speed performance of 1.3-μm InAs/GaAs quantum-dot lasers in a wide temperature range (5-50°C). Ridge waveguide devices with 1.1 mm cavity length exhibit small signal modulation bandwidths of 7.51 GHz at 5°C and 3.98 GHz at 50°C. Temperature-dependent K-factor, differential gain, and gain compression factor are studied. While the intrin...

Midinfrared unipolar photoluminescence in InAs/GaAs self-assembled quantum dots

We have investigated the midinfrared unipolar photoluminescence in InAs/GaAs self-assembled quantum dots. Resonant emissions between confined levels are clearly observed at low temperature at around 10 mm wavelength. The unipolar emissions are polarized either in the layer plane or along the z growth axis of the quantum dots. The emissions are associated with hole transitions that involve the g...
