Abstract:
AbstractThe current–voltage characteristics of n ^+-GaAs/ n ^0-GaAs/ N ^0-AlGaAs/ N ^+-AlGaAs/ n ^+-GaAs isotype heterostructures and n ^+-GaAs/ n ^0-GaAs/ n ^+-GaAs homostructures are studied. It is shown that, for a heterostructure under reverse bias providing the injection of electrons from n ^0-GaAs into N ^0-AlGaAs, the maximum operating voltage reaches a value of 48 V at a thickness of the N ^0-AlGaAs layer of 1 . 0 μm, and the current–voltage characteristic has no region of negative differential resistance. The operation of a homostructure is accompanied by a transition to the negative-

Abstract:
The fabrication of GaAs- and InP-based III-V semiconductor nanowires with axial/radial heterostructures by using selective-area metal-organic vapor-phase epitaxy is reviewed. Nanowires, with a diameter of 50–300 nm and with a length of up to 10 μm, have been grown along the〈111〉B or〈111〉A crystallographic orientation from lithography-defined SiO2mask openings on a group III-V semiconductor substrate surface. An InGaAs quantum well (QW) in GaAs/InGaAs nanowires and a GaAs QW in GaAs/AlGaAs or GaAs/GaAsP nanowires have been fabricated for the axial heterostructures to investigate photoluminescen

Abstract:
AlGaAs/GaAs heterostructures are the base of many semiconductor devices. The fabrication of new types of devices demands heterostructures with special features, such as large total thickness (~20 μm), ultrathin layers (~1 nm), high repeatability (up to 1000 periods) and uniformity, for which a conventional approach of growing such heterostructures is insufficient and the development of new growth procedures is needed. This article summarizes our work on the metalorganic vapour-phase epitaxy (MOVPE) growth of AlGaAs/GaAs heterostructures for modern infrared devices. The growth approaches presen

We investigate the influence of sputtered silica as annealing cap on the enhancement of intermixing rate of semiconductor quantum nanostructures. After sputtered silica application and subsequent rapid thermal annealing, we observed bandgap shift of over 200 meV with respect to the bandgap of as-grown material from various GaAs-based quantum well (QW) heterostructures such as GaAs/AlGaAs, InAlGaP/GaAs, and GaAs/AlGaAs systems at significantly lower temperature than the conventional dielectric cap process with plasma enhanced chemical vapor deposition (PECVD).

Abstract:
This thesis describes experimental and theoretical research into triple barrier resonant tunnelling structures which are attractive as potential high frequency oscillators in the terahertz frequency range. A lack of practical and coherent radiation emitters in this frequency range has resulted in it being named the \terahertz gap". However resonant tunnelling structures are seen as potential sources for practical solid state emitters which operate in this frequency range at room temperature.

The understanding and study of electron transport in semiconductor systems has been the instigation behind the growth of semiconductor electronics industry which has enabled technological developments that are part of our everyday lives. However, most materials exhibit diffusive electron transport where electrons scatter off disorder (impurities, phonons, defects, etc.) inevitably present in the system, and lose their momentum. Advances in material science have led to the discovery of materials which are essentially disorder-free and exhibit exceptionally high mobilities, enabling transport ph
