Intelligent states for angular momentum and Su(3) observables / by Benjamin R. Lavoie.
(2007)We generate expressions for all of the su(2) and su(3) intelligent states. To do so we combine well known coupling methods with unitary transformations; the construction is simple and efficient, and can be extended to ... -
Investigation of the Au-induced morphology of 3.8 and 12.3 degree silicon surfaces / by Wei Wu.
(2007)We have used a combination of scanning tunneling microscopy (STM) and low energy electron diffraction to investigate the Au-induced morphology of vicinal Si samples miscut from (111) by 3.8°, and 12.3° toward [112]. The ... -
Lattice vibrations induced by impurities in polar crystals
(1980)The effect of a single or a pair of polarizable impurities on the vibrational frequencies of a solid is investigated. It is shown that the introduction of impurities alters the energy of the crystal due to the coupling ... -
Luminescent response of phosphors and scintillators to ions with energies in the 0-100 KeV range
(1973)A survey of the ionoluminescence of a large number of ion-phosphor combinations under uniform conditions has been made. Powdered phosphors and scintillation crystals with different activators, different methods of surface ... -
Microwave interferometer for measuring dielectric properties of low-loss solids
(1974)An X-band microwave bridge-interferometer is constructed for measuring the permittivity of solids. Using simple theory, the system is first tested with several materials of known permittivity (e.g. ertalon, plexiglas ... -
Multiwavelength erbium-ytterbium co-doped fiber laser / by Mansour Dastmalchi.
(2007)A fiber ring laser, using erbium-ytterbium co-doped double clad fiber is proposed and demonstrated to produce a medium power multiwavelength fiber laser. The experimental results show that the ring resonator configuration ... -
Observation of bilayer growth in the initial epitaxy of pseudomorphic Mg on Mo(001)
(1999)Epitaxial growth of thin films on solid substrates is of great interest because it allows for the creation of materials with morphologies and chemical compositions which are not found in nature. The size o f electronic ... -
Optical spectroscopy of colon tissue and a breast cancer cell line : potential for cancer detection
(2004)Two forms of cancer affecting a large number of individuals are breast cancer and colon cancer. In 2003, it was projected that approximately 21000 Canadians would be diagnosed with breast cancer and another 18000 would ... -
Optically-excited excitonic states in semiconductor superlattices
(2002)An efficient method for calculation of the exciton states in type-I superlattices is developed and demonstrated. The model, based on the work of Dignam & Sipe [Phys. Rev. B 43,4097 (1991)], includes bound and quasi-continuous ... -
Photoluminescence and raman characterization of PLEE and MBE grown semiconductor epilayers
(1994)Photoluminescence and Raman investigations of selected alloy semiconductor epilayers are reported. Correlations relating optical spectra and a number of intrinsic and extrinsic properties of the materials studied are ... -
Photon number density operator
(1995)A new operator is introduced to represent the density of photons in configuration space. It has some features in common with operators previously introduced by Mandel and Cook but has better transformation properties. The ... -
Pressure dependent extrinsic effects in InSb
(1980)Electrical transport properties of n and p-type InSb in the temperature range 6.2-300K have been studied under pressures up to 15 kbar using Hall measurements. The donor gap in n-InSb is found to increase linearly with ... -
Self-assembly of dithiol monolayers on Au(III)
(2001)This thesis compares the self-assembly of octanethiol, a representative n-alkanethiol, with dithiothreitol (DTT) on Au (lll). Octanethiol is on eight carbon n-alkanethiol while DTT is a four carbon Q ,(i) dithiol ... -
Self-consistent driven Bloch oscillations in excitonic Wannier-Stark ladder
(2001)In this thesis, we present a theoretical model of Self-consistent driven Bloch oscillations (SCD BO) of different types of charge carriers in biased semiconductor superlattices photoexcited via ultra-short near-bandgap ... -
Simple route to new palladium-carbonyl-bis(diphenylphosphino)methane complexes
The method of synthesizing metal-carbonyl-dppm complexes [dppm = bis(diphenylphosphino)methane) devised by Holah and Hughes has been extended to include palladium. Specifically, reductions of palladium salts by NaBH4 ... -
Static dielectric properties of an ensemble of restricted one-dimensional oscillators
(1984)Deviations from constancy of the Clausius-Mossotti function, C[subscript M], with changes in density and temperature are considered on the basis of a one-dimensional oscillator model of the atom in which the valence ... -
The effects of propagational factors on quantum wires in close parallel proximity
(1993)Recent advances in semiconductor technology have made it possible to produce devices of such small size that electronic conduction through these devices is dominated by the quantum properties of the electron. The fact ... -
Theoretical study of the folding kinetics of the ultra-fast folding Trp-cage protein
(2006)Native-centric coarse-gained models, termed Ca Go models, have been widely used for computational simulation of small protein to study their folding kinetics and thermodynamics. The limitations of these models come from ... -
Thin gold films grown in ultra high vacuum on mica substrates
(2003)In-situ evaporation was used to deposit thin gold films (640 A) on mica substrates held at room temperature. The samples were characterized by Auger Electron Spectroscopy (AES) and Scanning Tunneling Microscopy (STM) ...
