Semiconductor quantum dots (QDs) are being regarded as the primary unit for a wide range of advanced and emerging technologies including electronics, optoelectronics, photovoltaics biosensing applications well domain q-bits based information processing. Such QDs suitable several novel device their unique property confining carriers 3-dimensionally creating discrete states. However, realization ...

Based on generalized quantum Langevin equations for the tight-binding wave function amplitudes and lattice displacements, electron and phonon quantum transport are obtained exactly using molecular dynamics (MD) in the ballistic regime. The electron-phonon interactions can be handled with a quasi-classical approximation. Both charge and energy transport and their interplay can be studied. We com...

Dietary antioxidants play an important role against oxidation, an underlying mechanism in the incidence of chronic diseases. Greens+ is a commercially available preparation containing a variety of plant-derived ingredients. The aim of the current study was to evaluate the antioxidant potential of the methanolic extract of greens+ powder using in vitro and in vivo techniques. In vitro studies we...

Address correspondence to [email protected] ABSTRACT In contrast to the static operations of conventional semiconductor devices, the dynamic conformational freedom in molecular devices opens up the possibility of using individual molecules as new types of devices such as a molecular conformational switch or for molecular data storage. Bistable molecules such as those having two stable c...

This work studies the diameter scaling behavior of broken-band GaSb/InAs vertical nanowire (VNW) Esaki diodes. A top-down fabrication process involving precise reactive-ion etching and alcohol-based digital etch has yielded devices with a tunneling junction below 10 nm. Clear peaks are observed an average peak current density 1MA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlin...
