• #### Controlled multi-step purification of single-walled carbon nanotubes ﻿

(2005)
A controlled and scalable multi-step purification method has been developed to remove iron impurity and non-nanotube carbon materials from raw single-walled carbon nanotubes produced in the HiPco (high pressure CO) process. ...
• #### Excimer laser induced electrical conductivity in polyimide: Applications to engineering, physics, and applied science ﻿

(1996)
Various aspects of the interaction of excimer laser pulses and polyimide were investigated, focusing on low fluences where laser induced electrical conductivity is observed. Multiple shot excimer ablation of polyimide was ...
• #### Impeded photo-oxidation of conducting polymer films using metal nanoshells ﻿

(2000)
Interest in the use of conducting polymers as the active layer in electroluminescent devices has grown steadily over the last decade, and the commercialization of such devices is imminent. The stumbling block to the ...
• #### Investigating self-assembly of functionalized nanotubes and peptides by tunneling microscopy ﻿

(2006)
Scanning tunneling microscopy (STM) is an ideal tool for probing the chemistry and physics of these types of nanostructures. Building upon on our previous carbon nanotube research, we have investigated thiol and thiophene ...
• #### Laser-assisted metalorganic chemical vapor deposition of zinc sulfide ﻿

(1997)
Laser-assisted metalorganic chemical vapor deposition (MOCVD) was used to grow crystalline zinc sulfide at temperatures as low as 200$\sp\circ$C. The metalorganic sources, dimethylzinc and diethylsulfide, were photodissociated ...
• #### Physical characterization of lithium niobate thin films on silicon substrates ﻿

(1988)
The structure and orientation of radio frequency sputtered lithium niobate (LiNbO$\sb3$) films on silicon substrates is determined using x-ray diffraction. The structure of the LiNbO$\sb3$ films is determined to be a strong ...
• #### Polyimide-based field effect transistor structures ﻿

(1999)
Because of the electrical insulating properties of polyimide, it is widely used in the packaging of semiconductor chips. However, it has been documented that the electrical resistivity can be decreased by several orders ...
• #### Reduced exchange coupling in perpendicular multilayers ﻿

(1997)
The ideal magnetic switching mechanism for magnetic recording is isolated domain coherent rotation. However, in typical Pd/Co and Pt/Co multilayers with high coercivity, the dominant switching mechanism is domain wall ...
• #### Resistive switching in silicon oxide-based systems ﻿

(2010)
Voltage-controlled resistive switching in various gap systems on SiO2 substrates is demonstrated. The nanosized gaps are made by several means using different materials including metals, semiconductors and amorphous carbon. ...

(2010)
In molecular and organic electronic systems, the electrode material has considerable influence on the performance of the resulting device. The advent of scanning tunneling microscopy (STM) and its various spectroscopic ...
• #### Transverse thermal conductivity of thin dielectric films ﻿

(1998)
Earlier work revealed that the transverse thermal conductivity of thin films of amorphous SiO$\sb2$ and $\rm Si\sb3N\sb4$ deposited on monocrystalline silicon decreased substantially when the film thickness was less than ...
• #### Ultrafast and magneto-optical spectroscopy of semiconductor heterostructures ﻿

(2012)
This thesis presents spectroscopic results using semiconductor heterostructures important for both applied and fundamental physics. First, we studied short-period superlattices of InAs and GaSb that suggest a promising ...
• #### Water-phase synthesis of cationic silica/polyamine nanoparticles ﻿

(2012)
Functionalizing surfaces with amine groups through the hydrolytic condensation of aminotrialkoxysilanes is a typical approach when modifying silica particles for use in bioimaging, enzyme immobilization, and other applications. ...
