Scaling of Trigate Junctionless Nanowire MOSFET With Gate Length Down to 13 nm

Matthieu Berthomé

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 ...

Flexoelectric effect in finite samples

Alexander Tagantsev

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 ...

Tri-Gate Normally-Off GaN Power MISFET

Elison de Nazareth Matioli, Bin Lu

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 ...

Diffraction and absorption enhancement from textured back reflectors of thin film solar cells

Christophe Ballif, Franz-Josef Haug, Ali Naqavi

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 ...

Analysis and design of terahertz antennas based on plasmonic resonant graphene sheets

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone

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 ...

Time-Resolved Photoinduced Thermoelectric and Transport Currents in GaAs Nanowires

Anna Fontcuberta i Morral

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 ...

Plasmonic nanoparticles for a bottom-up approach to fabricate optical metamaterials

Toralf Scharf

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 ...

Biomimetic soft lithography on curved nanostructured surfaces

Jürgen Brugger, Thomas Kiefer, Valentin Flauraud, Vaida Auzelyte

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 ...
