Orbitally selective breakdown of Fermi liquid quasiparticles in Ca1.8Sr0.2RuO4

Marco Grioni, Johan Juul Chang, Gianmarco Gatti

We present a comprehensive angle-resolved photoemission spectroscopy study of Ca1.8Sr0.2RuO4. Four distinct bands are revealed and along the Ru-O bond direction their orbital characters are identified through a light polarization analysis and comparison to ...

Surface-to-volume ratio controls the radiation of stratified plasmonic antennas

Olivier Martin, Christian Santschi, Banafsheh Abasahl

Surface plasmons are excited at a metal/dielectric interface, through the coupling between conduction electrons and incident photons. The surface plasmon generation is therefore strongly determined by the accessibility of the surface to the incoming electr ...

In-Plane-Gate GaN Transistors for High-Power RF Applications

Elison de Nazareth Matioli, Giovanni Santoruvo

In-plane-gatefield-effect transistors (IPGFETs) offer an innovative device architecture in which the channel conductivity is modulated by the electric field from the 2D electron gas in the two adjacent in-plane gates, isolated by etched trenches. The plana ...

Tuning the response of non-allowed Raman modes in GaAs nanowires

Anna Fontcuberta i Morral, Federico Matteini, Esther Alarcon Llado, Gözde Tütüncüoglu, Emanuele Uccelli, Francesca Amaduzzi, Hubert Hautmann

We report on the use of photonic resonances in Raman spectroscopy on single nanowires for the enhancement of forbidden modes and the study of the interaction of phonons with free-carriers. This is achieved by suspending nanowire over a trench and detecting ...

Role of the gate in ballistic nanowire SOI MOSFETs

Christian Enz, Jean-Michel Sallese, Anurag Mangla

In this paper we report the results of Monte-Carlo simulations performed on double-gate ballistic MOSFETs with a geometry such that the gates overlap only a fraction of the channel. We present a qualitative analysis of the simulation results highlighting t ...

Room-Temperature Ballistic Transport in III-Nitride Heterostructures

Elison de Nazareth Matioli

Room-temperature (RT) ballistic transport of electrons is experimentally observed and theoretically investigated in III-nitrides. This has been largely investigated at low temperatures in low band gap III-V materials due to their high electron mobilities. ...

Hematite photoelectrodes for water splitting: evaluation of the role of film thickness by impedance spectroscopy

Michael Graetzel, Kevin Sivula, Florian Le Formal

The electrochemical behavior of alpha-Fe2O3 photoelectrodes prepared by spray pyrolysis with different thicknesses was examined under dark and illumination conditions. The main charge transport phenomena occurring in the PEC cell photoelectrodes were chara ...

Spatially resolved photocurrents in graphene nanoribbon devices

Klaus Kern, Marko Burghard, Stephan Rauschenbach, Kannan Balasubramanian, Adarsh Singh Sagar, Thomas Dufaux

We present here a scanning photocurrent microscopy study of individual graphene nanoribbons, revealing pronounced photocurrent responses close to the nanoribbon/metal contacts. The magnitude of the corresponding photocurrent signal was found to be directly ...

Comparison between front- and back-gating of Silicon Nanoribbons in real-time sensing experiments

Carlotta Guiducci, Enrico Accastelli, Giulia Cappi, Thomas Ernst

Field-effect transistors (FETs) with open gate structures such as Silicon Nanoribbons (SiNRs) are promising candidates to become general platforms for ultrasensitive, label-free and real-time detection of biochemical interactions on surface. This work prop ...
