Ohmic Behavior in Metal Contacts to n/p-Type Transition-Metal Dichalcogenides: Schottky versus Tunneling Barrier Trade-off
High contact resistance (RC) between 3D metallic conductors and single-layer 2D semiconductors poses major challenges toward their integration in nanoscale (opto)electronic devices. While in experiments the large RC values can be partly due to defects, ab initio simulations suggest …

A nanoguitar with adjustable 2D materials
The frequency of a musical instrument, such as a guitar string, is tunable over more than one octave, i.e. a ratio of two between the maximum and minimum frequency. It is defined as f=(k/m)^0.5 where k is the spring …

ERC Consolidator Grants 2022 : Daniel Lanzilloti Kimura, Laureate for the T-RECS project
Acoustic phonons are usually seen as a primary source of unwanted effects in electronics, optoelectronics, and quantum technologies based on solid-state platforms. This project proposes a series of tunable nanodevices where acoustic phonons constitute, instead, a central resource to …

ENTENTE project : Laureate of the CNRS RISE programme
Rémy Braive and Giuseppe Modica, with the support of Robert Horvath, all three researchers at C2N, have developed a new technology for integrated frequency generators on a chip based on the concepts of optomechanics (interaction between optics and acoustics).

Quasiparticle Andreev scattering in the ν = 1/3 fractional quantum Hall regime
The scattering of exotic quasiparticles may follow different rules than electrons. In the fractional quantum Hall regime, a quantum point contact (QPC) provides a source of quasiparticles with field effect selectable charges and statistics, which can be scattered on …
