Nano-Fabricated Free-Standing Wire-Scanners with Sub-Micrometer Resolution
G. L. Orlandi, C. David, E. Ferrari +10
Diagnostics of the beam transverse profile with ever more demanding spatial resolution is required by the progress on novel particle accelerators - such as laser and plasma driven…
Fluorescence Excitation by Enhanced Plasmon Upconversion under Continuous Wave Illumination
Mehmet Emre Tasgin, Ildar Salakhutdinov, Dania Kendziora +6
We demonstrate effective background-free continuous wave nonlinear optical excitation of molecules that are sandwiched between asymmetrically constructed plasmonic gold nanoparticl…
High-performance planar light-emitting diode
Marco Cecchini, Vincenzo Piazza, Fabio Beltram +5
Planar light-emitting diodes (LEDs) fabricated within a single high-mobility quantum well are demonstrated. Our approach leads to a dramatic reduction of radiative lifetime and jun…
Resonant Transport in Nb/GaAs/AlGaAs/GaAs Microstructures
F. Giazotto, P. Pingue, F. Beltram +4
Resonant transport in a hybrid semiconductor-superconductor microstructure grown by MBE on GaAs is presented. This structure experimentally realizes the prototype system originally…
Reflectionless tunneling in planar Nb/GaAs hybrid junctions
Francesco Giazotto, Marco Cecchini, Pasqualantonio Pingue +5
Reflectionless-tunneling was observed in Nb/GaAs superconductor/semiconductor junctions fabricated through a two-step procedure. First, periodic -doped layers were grown by mole…
Evidence of two-electron tunneling interference in Nb/InAs junctions
Antonio Badolato, Francesco Giazotto, Marco Lazzarino +4
The impact of junction transparency in driving phase-coherent charge transfer across diffusive semiconductor-superconductor junctions is demonstrated. We present conductivity data…
Andreev reflection in engineered Al/Si/InGaAs(001) junctions
S. De Franceschi, F. Giazotto, F. Beltram +3
Complete suppression of the native n-type Schottky barrier is demonstrated in Al/InGaAs(001) junctions grown by molecular-beam-epitaxy. This result was achieved by the insertion of…
Andreev reflection in Si-engineered Al/InGaAs hybrid junctions
Silvano De Franceschi, Francesco Giazotto, Fabio Beltram +3
Andreev-reflection dominated transport is demonstrated in Al/n-In0.38Ga0.62As superconductor-semiconductor junctions grown by molecular beam epitaxy on GaAs(001). High junction tra…
