Zinc tin oxide (ZTO) films deposited by pulsed laser deposition (PLD) are
investigated as a channel layers for transparent thin-film transistors (TTFTs).
Films are deposited on glass for characterization, and transistor channel layers are
deposited onto aluminum oxide-titanium oxide/tin doped indium oxide/glass
substrates (ATO/ITO/glass) to produce TTFTs.

Lipids, especially phospholipids, are very common
but important molecules found in cells and animal
tissue, performing many biological functions, particularly
in membranes. Lipids, when mixed with water,
spontaneously form ordered systems, such as micelles,
vesicles and multibilayers. The size of these systems
and their degree of ordering depend on the...
The electrical properties of amorphous and crystalline titanium dioxide polymorphs are reported. Titanium dioxide is a widely used transparent semiconductor and it is a useful oxide model. Using variable temperature transport measurements of thin films, it was possible to establish the activation energy barrier for conduction. This was accomplished using...
Brownian motion is the movement of a particle in a fluid resulting from collisions with surrounding molecules. It has modern applications in simulating fluid dynamics and the motion of proteins in biophysics. Brownian motion simulations generally evolve the initial state by applying Newton’s second law to every particle. These simulations...
High resolution images of a dim companion in a binary star system can be obtained using a Digital Micromirror Array (DMA) as an optical mask. Imaging can be problematic because the intense light from the main star can saturate the detector and leave the companion unnoticed. Placement of the DMA...
We exhibit long-lived resonances in scattering from two-dimensional soft cage potentials comprised of three and four Gaussian peaks. Specific low-energy resonances with very narrow width are shown to correspond to classical multiple-reflection events. These states have much larger probability densities inside the cage than outside and mimic bound states in...
