Single- and multi- cavity beam masers for microwave and ultramicrowave frequencies
Thesis
Single- and multi- cavity beam masers for microwave and ultramicrowave frequencies. https://keele-repository.worktribe.com/output/410516

An amnonia beam maser with a single resonant cavity and with two cascaded cavities is investigated.
A single cavity microwave beam maser is described and its characteristics of operation determined. This maser is constructed so that a second resonan... Read More about Single- and multi- cavity beam masers for microwave and ultramicrowave frequencies.

Ionization in oxygen being a thesis on the measurement of ionization and attachment coefficients in low pressure oxygen discharges
Thesis
Ionization in oxygen being a thesis on the measurement of ionization and attachment coefficients in low pressure oxygen discharges. https://keele-repository.worktribe.com/output/410517

Ionization processes in oxygen have been studied using a Townsend type apparatus 'using electron swarms of mean energy of about a few electron volts. From a measurement
of currents and gap distances the ionization and attachment coefficients have be... Read More about Ionization in oxygen being a thesis on the measurement of ionization and attachment coefficients in low pressure oxygen discharges.

Some electrical properties of alkaline earth oxides with particular reference to oxide-coated cathodes
Thesis
Some electrical properties of alkaline earth oxides with particular reference to oxide-coated cathodes. https://keele-repository.worktribe.com/output/410407

The electrical conductivity and thermionic emission from
cathodes coated with barium oxide and a mixture of barium and strontium oxides has been studied as a function of temperature in the range 2900 - 10000 degrees K employing cylindrical diodes co...

An electron resonance study of myoglobin single crystals
Thesis
An electron resonance study of myoglobin single crystals. https://keele-repository.worktribe.com/output/410415

The g-value end line width variations of the electron resonance spectrum, from single crystals of acid met myoglobin, have been measured in both 'high spin' and 'low spin' derivative form. The g-value variation is discussed in conjunction with the pr... Read More about An electron resonance study of myoglobin single crystals.

Work function changes of clean and contaminated metal films in vacuum and in hydrogen
Thesis
Work function changes of clean and contaminated metal films in vacuum and in hydrogen. https://keele-repository.worktribe.com/output/410419

This investigation is concerned with changes in the work functions of evaporated metal films caused by gas adsorption and variations in temperature. The importance of such changes is underlined by a description of the work function dependent discharg...

Primary and secondary ionization processes in mercury vapour
Thesis
Primary and secondary ionization processes in mercury vapour. https://keele-repository.worktribe.com/output/410425

Because of the important industrial applications of mercury, most work in the field of mercury vapour discharges has been carried out On mercury vapour arcs. The work described in this thesis is concerned with the fundamental processes operative in m... Read More about Primary and secondary ionization processes in mercury vapour.

Work function changes of clean and contaminated metal films in vacuum and in mercury vapour
Thesis
Work function changes of clean and contaminated metal films in vacuum and in mercury vapour. https://keele-repository.worktribe.com/output/410430

Considering the important industrial applications of mercury it is remarkable that so little work has been carried out on the characteristics of mercury surfaces. Prior to the present work, the last determination of the work function of mercury was d...

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...
