Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost. However, current experiments and proofs of concept rely on free-space ultrafast pump lasers and rather complex…

Thermodynamics of a single mesoscopic phononic mode

Ilya Golokolenov, Arpit Ranadive, Luca Planat, Martina Esposito, Nicolas Roch, Xin Zhou, Andrew Fefferman, Eddy Collin

In recent decades, the laws of thermodynamics have been pushed down to smaller and smaller scales, within the field of stochastic thermodynamics and state-of-art experiments performed on mesoscopic systems. But these measurements concern mostly thermal properties of electrons and photons. Here we…

SiGe quantum wells implementation in Si based nanowires for solar cells applications

M. Safi, A. Aissat, H. Guesmi, Jean-Pierre Vilcot

This study focuses on modelling and optimizing a new Si nanowire solar cell containing a SiGe/Si quantum well. Quantum efficiency measurements show that the proposed structure has a higher energy absorption advantage and stronger than that of a solar cell based on a standard Si p-i-n nanowire. As a…

Compact localized boundary states in a quasi-1D electronic diamond-necklace chain

S. Kempkes, Pierre Capiod, S. Ismaili, J. Mulkens, L. Eek, I. Swart, C. Morais Smith

Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date exhibit a wave function that decays exponentially into the bulk and hybridizes with other nearby zero-modes, thus…

Silicon Compatible Process To Integrate Impedance Cytometry With Mechanical Characterization

Quentin Rezard, Faruk Azam Shaik, Jean Claude Gerbedoen, Fabrizio Cleri, Dominique Collard, Chann Lagadec, Mehmet Tarhan

We introduced 3D silicon electrodes to perform impedance cytometry on single cells without compromising practical integration with sensors measuring complementary properties, e.g., mechanical properties. Microfabricated from a highly-doped SOI wafer, some design modifications were made to improve…
