Resonant graphene antennas used as true interfaces between terahertz (THz) space waves and a source/detector are presented. It is shown that in addition to the high miniaturization related to the plasmonic nature of the resonance, graphene-based THz antenn ...
Static flexoelectric effect in a finite sample of a solid is addressed in terms of phenomenological theory for the case of a thin plate subjected to bending. It has been shown that despite an explicit asymmetry inherent to the bulk constitutive electromech ...
In this letter, we report the performance of high-kappa/metal gate nanowire (NW) transistors without junctions fabricated with a channel thickness of 9 nm and sub-15-nm gate length and NW width. Near-ideal subthreshold slope (SS) and extremely low leakage ...
Silicon technology has advanced through the past four decades at exponential rate both in performance and productivity. Along with the miniaturization, the power demand grew also exponentially. New technologies are studied in order to develop switches that ...
We investigate experimentally metallic nanoparticle composites fabricated by bottom-up techniques as potential candidates for optical metamaterials. Depending on the plasmonic resonances sustained by individual NPs and their nanoscale organization into lar ...

We study light scattering and absorption in thin film solar cells, using a model system of a sinusoidally textured silver reflector and dielectric layers of ZnO and amorphous silicon. Experimental results are compared to a theoretical model based on a Rayl ...
In order to clarify the temporal interplay of the different photocurrent mechanisms occurring in single GaAs nanowire based circuits, we introduce an on-chip photocurrent pump-probe spectroscopy with a picosecond time resolution. We identify photoinduced t ...
In this paper a nano-molding process using a nature-created master is demonstrated. The eye of night moth Agotis Exclamationis having 100 nm-scale structures on a curved surface is used as biomimetic master mold from which nanostructures are replicated ont ...
Atomistic simulations show that organosilicates, used as low permittivity dielectric materials in advanced integrated circuits, can be made substantially stiffer than amorphous silica, while maintaining a lower mass density The enhanced stiffness is achiev ...
We present a new normally-off GaN transistor-the tri-gate normally-off GaN metal-insulator-semiconductor field-effect transistor (MISFET). Due to the excellent channel control of a new 3-D gate structure, a breakdown voltage of 565 V has been achieved at a ...
