Illumination of hafnium dioxide (HfO2) thin films with a nanosecond pulsed laser reaching peak intensities of 180 GW / cm2 has been shown to trigger a laterally expanding plasma wave prior to ablation that reaches speeds of up to 100 km / s. The phen

An ion-beam sputtered film of hafnium oxide was irradiated with an intense nanosecond laser pulse above the ablation threshold. The transmitted laser power was measured as a function of time, with a resolution of a few hundred picoseconds. The spatia

Nongeminate charge recombination occurs over a broad range of time scales in polymer solar cells and represents a serious loss channel for the performance and lifetime of devices. Multiple factors influence this process, including changes in morpholo

We report on a general theoretical approach to study exciton transport and emission in a single-walled carbon nanotube (SWNT) in the presence of a localized surface-plasmon (SP) mode within a metal nanoparticle interacting via near-field coupling. We

The time-of-flight (TOF) current transients from solution-cast, free-standing films of p-diethylaminobenzaldehyde diphenyhydrazone in bisphenol A polycarbonate (DEH:PC) have been studied using electron gun induced charge generation. Changes in the sh

The mechanism of charge transport in molecularly doped polymers has been the subject of much discussion over the years. In this paper, data obtained from a new experimental variant of the time-of-flight (TOF) technique, called TOF1a, are compared to

A new analytical method for determining trap distribution from a transient photocurrent in time-of-flight (TOF) measurements has been proposed in the context of convection diffusion equation with multiple-trapping and detrapping processes. The method

Pump-dependent photoluminescence imaging and 2nd order photon correlation studies have been performed on individual single-walled carbon nanotubes (SWCNTs) at room temperature that enable the extraction of both the exciton diffusion constant and the

Organic electrochemical transistors (OECTs) are receiving a great deal of attention as transducers of biological signals due to their high transconductance. A ubiquitous property of these devices is the non-monotonic dependence of transconductance on
