A continuous flow of hot electrons that are not at thermal equilibrium with the surrounding metal atoms is generated by the absorption of photons. Here we show that hot electron flow generated on a gold thin film by photon absorption (or internal photoemission) is amplified by localized surface plasmon resonance. This was achieved by direct measurement of photocurrent on a chemically modified g...

The fabrication of organic thin film transistors with highly reproducible characteristics presents a very challenging task. We have prepared and analyzed model pentacene thin film transistors under ultra-high vacuum conditions, employing surface analytical tools and methods. Intentionally contaminating the gold contacts and SiO2 channel area with carbon through repeated adsorption, dissociation...

Organic and polymeric semiconductor-based thin-film fieldeffect transistors (OFETs) are of great interest for low-cost largearea memories and driving circuits in display applications.1 In these organic devices, the charge carrier transport is dominated by the hopping mechanism at room temperature.2 Therefore, highly ordered thin films with large interconnected polycrystalline grains are necessa...

High-quality thin films of conjugated molecules with smooth interfaces are important to assist the advent of organic electronics. Here, we report on the layer-by-layer growth of the organic semiconductor molecule p-sexiphenyl (6P) on the transparent electrode material graphene. Low energy electron microscopy and micro low energy electron diffraction reveal the morphological and structural evolu...

The scattering properties of transparent conductive oxide (TCO) films into dielectric and semiconductor surrounding media are modeled and compared to experiment. The new approach is not only valid for smooth optical films but also for films with enhanced roughness in order to generate light trapping structures for thin film solar cells. ©2010 Optical Society of America.

Semiconductor processing in manufacturing must be fast and highly accurate in the measuring of the surface profile of soft thin films such as photoresist. Since photoresist surface is very smooth and deformable, a device to measure is required that will measure vertical direction with a nanometer resolution in height and not damage the film during the measurement. To do this, we developed an ap...

Plasmonic light trapping in thin film solar cells is investigated using full-wave electromagnetic simulations. Light absorption in the semiconductor layer with three standard plasmonic solar cell geometries is compared to absorption in a flat layer. We identify near-field absorption enhancement due to the excitation of localized surface plasmons but find that it is not necessary for strong ligh...
