Growth, optical properties and device characterisation of InAs/GaAs quantum dot bilayers
The growth and optical properties of InAs/GaAs quantum dot (QD) bilayers are investigated, where the strain interactions between closely spaced QD layers are exploited to tailor the optical properties of the system. The underlying (seed) layer acts as a template for subsequent growth of the upper layer, whose properties can then be modified due to the greater freedom in the choice of growth con...
متن کاملSelf-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...
متن کاملWavelength and polarization variations of InAs/GaAs quantum dots emission at liquid Helium temperature via microphotoluminescence spectroscopy
In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...
متن کاملInterdot carrier transfer in asymmetric bilayer InAs/GaAs quantum dot structures
Transient photoluminescence from a series of asymmetric InAs quantum-dot bilayers with a GaAs barrier layer thickness varying from 30 to 60 monolayers between the quantum-dot planes is investigated. The interdot carrier transfer process is analyzed. In the framework of a three-level system, interdot carrier transfer times between 200 and 2500 ps are derived and compared with similar data from t...
