A compact optomechanical gigahertz oscillator made of a piezoelectric III-V semiconductor

A team of physicists at C2N and Thalès Research and Technology have demonstrated an optomechanical oscillator, based on an ultra-compact bichromatic one-dimensional crystal, able to operate at 3 GHz at room temperature. Oscillators are devices able to produce ...

Mimicking potentials for acoustic-phonons by shaping their propagation through a nanoengineered structure

In a theoretical work, a team of researchers at C2N has proposed a novel nanoengineered approach to manipulate the way acoustic-phonons travel through a periodic structure. They have demonstrated that their phononic platform allows studying a variety of potentials ...

Generation of light in a photon-number quantum superposition

Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all. They showed that the same kind of light emitters ...

Ultrathin solar cells reach a record of nearly 20% efficiency

Researchers at the Centre de Nanosciences et de Nanotechnologies (C2N), in collaboration in particular with researchers at the German Fraunhofer ISE, have succeeded to trap sunlight efficiently in a solar cell thanks to an ultrathin absorbing layer made of ...
