Tetrazine-incorporating layered halide perovskites featuring type II electronic interface: a small cation with several optical and electronic resonances

Layered halide perovskites are a class of semiconductors easily produced via chemical approaches and showing unique optical and electronic properties. These materials have a natural quantum-well electronic structure, that is, the band-gap of the…

Supraconductivité

Towards room-temperature superconductivity

By taking advantage of a stability criterion established recently, the critical temperature Tc is reckoned with help of the microscopic parameters, characterising the normal and superconducting electrons, namely the independent-electron band…

New method for residual amplitude modulation control in fibered optical experiments

When locking the frequency of a laser to an optical cavity resonance, the residual amplitude modulation (RAM), which accompanies the phase modulation necessary to build the error signal, is a major limitation to the frequency stability. We show that…

Imaging through fog using quadrature lock-in discrimination

We report experiments conducted in the field in the presence of fog, that were aimed at imaging under poor visibility. By means of intensity modulation at the source and twodimensional quadrature lock-in detection by software at the receiver, a…
