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...

The synthesis and photochemical behaviour of benztropones and related compounds
Thesis
The synthesis and photochemical behaviour of benztropones and related compounds. https://keele-repository.worktribe.com/output/415123

Our aim was to identify the possible factors which controlled the photochemical reactions of benztropones or more widely , annulated tropones,by synthesising benztropones with electron-donating and electron-withdrawing substituents on the benzene rin...

Adaptive filters for two to four wire conversion in telephony
Thesis
Adaptive filters for two to four wire conversion in telephony. https://keele-repository.worktribe.com/output/415139

The problem of inaccurate two to four wire conversion is considered, and a conprehensive survey of the transhybrid responses of 1845 subscribers' lines is carried out.
Results on the optimum performance achieved by line matching techniques are prese... Read More about Adaptive filters for two to four wire conversion in telephony.

Stereochemical studies of heterocyclic analogues of decalins
Thesis
Stereochemical studies of heterocyclic analogues of decalins. https://keele-repository.worktribe.com/output/415140

This dissertation is concerned with the synthesis of the
octahydro-1-benzopyran and octahydro-1,4-benzoxazine systems and the application of 1H and 13C n.m.r. spectroscopy to determine the stereochemistry and major conformation adopted by the isomer... Read More about Stereochemical studies of heterocyclic analogues of decalins.

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...
