Acoustoelectric effect in semiconductors / by S. B. Joshi
The possibility of electron temperature decreasing below the lattice temperature in the presence of an external electric field (electron cooling) has been pointed out by Paranjape and Ambrose (1964). In the present works ... -
Amorphous selenium (a-Se) avalanche photodetector for applications in positron emission tomography (PET)
(2012-11-10)Although avalanche amorphous selenium (a-Se) is a very promising photoconductor for a variety of imaging applications, it is currently restricted to applications with electron beam readout. This is performed with a vacuum ... -
Computer simulation of functional materials for therapeutic ultrasound applications
(2015-01-13)Magnetic resonance imaging guided high intensity focused ultrasound is a potential non-invasive treatment which uses constructive interference patterns to concentrate ultrasound energy generated by a piezoelectric ... -
Correspondence rules in SU (3)
(2018)In this thesis, I present a path to the correspondence rules for the generators of the su(3) symmetry and compare my results with the SU(2) correspondence rules. Using these rules, I obtain analytical expressions for the ... -
Curvature-density functional theory of shape transformation in vesicles of two-component lipid systems
(2006)The shape transformations and composition variation of two-component model lipid membrane isolated vesicles are studied. These are studied as aggregates in low concentration solutions so that the vesicles are isolated ... -
Degenerate four wave mixing in biased semiconductor superlattices
(2001)Includes material on semiconductor Bloch equations, the Wannier-Stark ladder and Bloch oscillation theory. It also develops the equations of motion which allow calculation of the DFWM signal for biased semiconductor ... -
Development of nonlinear 3-D, and novel 2-D optical microscope imaging systems for time-lapse imaging
(2004)The design and development of a nonlinear two-photon, 3-D microscope imaging system, software for manipulation of 2-D and 3-D images, and the operation of a novel 2-D imaging system used for monitoring cultured live cell ... -
Dielectric and infrared studies of radio frequency processes in some alcohols / by Humayun Mandal
(1988)In this thesis, the results of dielectric studies on a number of aliphatic alcohol molecules with variable chain lengths are presented. This investigation was complemented by infrared and viscosity measurements. Dielectric ... -
Diffusion of impurities from ion implants in silicon / Janis Rozenbergs. --
(1974, c197)The use of shallow single and double impurity ion implants as diffusion sources was studied on bare (111) silicon wafers implanted at room temperature with 45 KeV boron, phosphorus and arsenic. The samples were diffused ... -
Effect of a strong magnetic field on the Mott Transition in Semiconductors / by D. G. Hughes
(1970)This thesis considers the effect of a magnetic field on the transition from a conducting to a non-conducting state in impurity semiconductors, with particular reference to indium antimonide. Two models for such a ... -
Effects of selected mountain bike front suspension forks on handlebar vibration and ground reaction forces
(1997)The purpose of this investigation was to compare the effectiveness of two types of mountain bike front fork suspension systems for controlling ground reaction vibration at the handlebar upon impacting a raised surface. ... -
Elastic and inelastic scattering of conduction electrons from oscillating impurities in semiconductors.
(1977)Elastic scattering and inelastic scattering of conduction electrons by oscillating ionized impurities in semiconductors have been analyzed on the assumption that the scattering potential is the Coulomb potential between ... -
Electrical conduction in nylon fibre and cellulosic capacitor tissue / by J. E. Hanneson
(1970)The experiments described in this work are divided into two main parts. The first is concerned with electrical properties of a single filament of nylon held between two tungsten hook-electrodes. Currents were observed ... -
Electron-photon interactions in quantum dots : coupled oscillators
(1995)A coupled oscillator model is developed for the far infra-red response of a quantum dot, and this model is used to predict the vacuum-held Rabi splittings of a dot-cavity system. -
Energy states of a hydrogen atom placed between two metal slabs
(1998)In this thesis, we utilize the hydrodynamical model to evaluate the potential energy and self-energy for an electron and a hydrogen atom placed between two semi-infinite metal slabs. The potentials and self-energies are ... -
Evaporation of highly charged waterdrops in the atmosphere / by Yean Ming Huang. --
(1975)The evaporation of charged waterdrops is accompanied by negligible loss of charge; consequently, as the surface area falls, the electrostatic pressure increases. When a critical value is reached, one or more highly charged ... -
Exciton operators : commutation relations and dynamics
(1997)The electron-hole pair operator commutation relations for a semiconductor are explicitly derived showing that the pairs are quasi-bosons with statistics intermediate between bosons and fermions. These pair operators are ... -
Gold-induced nanostructuring of silicon surfaces
(2005)In this thesis, a combination of scanning tunneling microscopy and low energy electron diffraction is used to investigate how submonolayer amounts of Au affect the large scale surface morphology of a vicinal Si sample ...
