TL;DR: A broadband photodetector using a layered black phosphorus transistor that is polarization-sensitive over a bandwidth from ∼400 nm to 3,750‽nm is demonstrated and might provide new functionalities in novel optical and optoelectronic device applications.

TL;DR: It is shown that several different two-dimensional atomic crystals, such as molybdenum disulfide and tungsten diselenide, can be intercalated with quaternary ammonium molecules of varying sizes and symmetries to produce a broad class of superlattices with tailored molecular structures, interlayer distances, phase compositions, electronic and optical properties.

TL;DR: The results underscore the relatively large optical nonlinearity of BP with unique polarization and thickness dependence, and its potential for polarized optical pulse generation, paving the way to BP based nonlinear and ultrafast photonic applications (e.g., ultrafast all-optical polarization switches/modulators, frequency converters etc.).

TL;DR: In this article, a single crystal of Rb{}_{0.88}$Fe${}_{1.81}$Se${}-2} was grown, which showed a clear superconducting transition in magnetic susceptibility and electrical resistivity.

TL;DR: In this article, the evolution of superconductivity in an FeSe thin flake with systematically regulated carrier concentrations by the liquid-gating technique was reported, and it was shown that simple electron-doping process is able to induce high-temperature superconductions with an onset at 48 K.
