    Sensitive mid-infrared detection in wide-bandgap semiconductors using extreme non-degenerate two-photon absorption

    Identifying strong and fast nonlinearities for today's photonic applications is an ongoing effort1. Materials2,3,4,5 and devices6,7,8,9 are typically sought to achieve increasing nonlinear interactions. We report...

    Enhanced carrier multiplication in engineered quasi-type-II quantum dots

    One process limiting the performance of solar cells is rapid cooling (thermalization) of hot carriers generated by higher-energy solar photons. In principle, the thermalization losses can be reduced by convert...
