  1. Ultrafast carrier dynamics and enhanced electroabsorption in (gallium,indium)arsenide/(aluminum,indium)arsenide asymmetric double quantum well structures

    Krol, Mark Francis.The University of Arizona.1995

    … hole tunneling in (Ga,In)As/Al,In)As asymmetric double quantum wells (ADQWs) is presented. A single time constant is observed at low carrier densities indicating the holes tunnel from the narrow well (NW) to the wide well (WW) at least as fast as electrons. At high carrier densities a two …

  2. III-V Bismide Optoelectronic Devices

    Fan, Dongsheng2016

    … GaSb-based type-I InGaAsSb/AlGaInAsSb quantum well laser diodes in 3-4 um mid-wavelength range, the lasing wavelength and performance of the devices are limited due to the lack of hole confinement in the active regions. In this dissertation, a novel GaSb-based GaInAsSbBi material is …

    Bregenzer, Josef JohannUniversity of Glasgow2010

    … laser diode on an unstrained GaAs/AlGaAs double quantum well heterostructure material system. A predominantly TM polarised optical output from the converter facet of greater than 80% is demonstrated for a converter length of 20 μm at an emitting wavelength of 867.1 nm. The about 1.4 mm …

  4. Experimental Realisation of Energy Harvesters built from Quantum Dots and Quantum Wells

    Jaliel, GulzatUniversity of Cambridge2020

    … harvester built from two resonant-tunnelling quantum dots. A device, proposed by Jordan et al. [1], harvests energy from an area of 90 μ m2 of a two-dimensional electron gas (2DEG), using the energy-selective transport of electrons through a pair of quantum dots. It has proven to be an …
