Studies relating to cyclotron emission from semiconductors
(University of St Andrews, 1985) - ThesisIn this thesis studies relating to cyclotron emission in GaAs, InSb, InP and CdₓHg₁- ₓTe (C.M.T.) are described. The effect of the electric field bias on the emission intensity and linewidth in GaAs and InP is studied and ... -
Exciton saturation dynamics and spin gratings in multiple quantum well semiconductors
(University of St Andrews, 1997) - ThesisThe dynamics of exciton saturation in GaAs/AlGaAs multiple quantum wells are investigated using picosecond optical pulses. The main contributions to exciton saturation have been shown to be phase space filling. Coulomb ... -
A study of the high temperature superconductor YBa₂Cu₃O₇-𝛿 and its cobalt-doped derivative
(University of St Andrews, 1994) - ThesisStatic nuclear magnetic resonance (NMR) techniques have been used to study the magnetic hyperfine interactions of ⁶³Cu and ⁸⁹Y nuclei in the superconducting (T=1.5K) and normal (T=160-300K) states of the pure and cobalt ... -

Ferroelectricity in potassium dihydrogen phosphate
(University of St Andrews, 1951) - ThesisA brief survey of ferroelectrics and a statement of the purpose of the present research are given. The necessary piezoelectric equations are developed and, using Mueller’s theory of Rochelle salt as a basis, a phenomenological ...
