Magneto-optical spectroscopy of metallic carbon nanotubes
Through polarization-dependent magneto-optical absorption spectroscopy, the magnetic susceptibility anisotropy for metallic single-walled carbon nanotubes has been extracted and found to be up to 4x greater than values for ...
A theoretical study of cluster reactivity and the effects of electric field on adatom-surface bond
We have used the density functional ab initio method to study the reactivity of small clusters (ammonia reacting with GaAs clusters), and the effects of electric field on adatom-surface interactions (H and Al adsorbed on ...
Fabrication of optically active nanostructures by chemical methods
A new method of fabricating long-range, planar arrays of discrete, submicron metal structures on glass or SiO2/Si surfaces has been developed without the use of resist masks or chemical etching. The approach combines ...
The hardness and modulus of molybdenum/aluminum oxide microlaminates as determined by nanoindentation
The elastic modulus and hardness of 1.2 $\mu$m thick films made of alternating and equal layers of sputter deposited Mo and Al$\sb2$O$\sb3$ were measured by a depth-sensing indentation apparatus which can test the properties ...
Polarization reversal in thin film lithium niobate on silicon
The spontaneous polarization of thin film LiNbO$\sb3$ has been shown to be reversible with the application of an electric field at room temperature. This electric field is applied across the sample in the form of a voltage ...
The cooling of a surface, due to photoelectric emission
The cooling of a surface when thermionic electrons are emitted has been measured by Richardson and others. The results obtained for tungsten and other metals are consistent with recent determinations of the work functions ...
Adiabatic thermal changes in dielectrics at low temperatures
The problem set up as the objective of the present thesis is the detection and measurement of adiabatic thermal changes in barium titanate ceramic at low temperatures. Concurrent with this is the problem of devising ...

Towards the quantum limit: A Single Electron Transistor analysis
The Single Electron Transistor (SET), especially its variation the radio frequency single electron transistor (RF-SET), is a fast and ultra-sensitive electrometer working in the vicinity of the quantum limit. In this thesis, ...
Wet-spinning of neat single-walled carbon nanotube fiber from 100+% sulfuric acid
Single-Walled Carbon Nanotubes (SWNT) have been found to have excellent solubility in super acids such as 100+% H2SO4, and chlorsulfonic acid. The solutions display liquid crystalline behavior at high concentrations in ...
