Novel Approaches To The Fabrication Of Nanoscale Devices
Thesis
Novel Approaches To The Fabrication Of Nanoscale Devices. https://keele-repository.worktribe.com/output/415053

This thesis describes the effects of a post-growth hydrogenation on as-grown samples and device structures based on III-N-V and III-V semiconductor compounds. The spectral response of quantum wells (QWs) or superlattices (SLs) are tuned by the contro... Read More about Novel Approaches To The Fabrication Of Nanoscale Devices.

Laser Writing of the Electronic Activity of Nitrogen and Hydrogen Atoms in Gallium Arsenide
Thesis
Laser Writing of the Electronic Activity of Nitrogen and Hydrogen Atoms in Gallium Arsenide. https://keele-repository.worktribe.com/output/415054

In this study, we use a focussed laser beam to control the electronic activity of N- and H-atoms in a dilute nitride Ga(AsN)/GaAs quantum well (QW). We find that the laser can be used to dissociate N-H complexes in hydrogenated Ga(AsN) thus enabling...

An A.E.S. study of S.E.E. and electron beam effects at oxygen exposed aluminium surfaces
Thesis
Adem, E. H. An A.E.S. study of S.E.E. and electron beam effects at oxygen exposed aluminium surfaces. https://keele-repository.worktribe.com/output/415251

An AES technique has been used to Investigate oxygen adsorption at clean polycrystalline aluminium surfaces. The adsorption process was found to consist of two stages: chemisorption, reached within the first 50L of oxygen exposure, is followed by an...
