  • Mid-infrared light emitting diodes (LEDs) based on black phosphorus (BP) have shown promising performance, but they are usually limited by the environmental instability of the material. Here, the authors extrapolate a room-temperature operational lifetime of BP LEDs up to ~ 15,000 h via Al2O3 passivation and nitrogen seal packaging.

  • Black phosphorus (BP) is considered a promising van der Waals material for the realization of mid-infrared detectors. Here, the authors report the realization of flexible infrared imagers based on solution-processed BP photodiodes on thin plastic substrates, showing long term stability and mechanical robustness.

  • Out-of-plane ferroelectricity is usually unstable in the two dimensional limit due to the presence of the depolarization field. Here, the authors successfully circumvent this issue by growing µm-sized SnS monolayers that exhibit in-plane ferroelectricity that is stable at room temperature.
