Abstract

Researchers have developed a bolometer using bilayer graphene with a bandgap tuned by electric fields; Researchers at Brown University (U.S.A.) create a single-material laser that provides red, green or blue laser light; Researchers at the Massachusetts Institute of Technology (U.S.A.) have devised an all-carbon, near-infrared photovoltaic cell filled with single-walled nanotubes; In a development that brings practical quantum computers closer to reality, a team of researchers demonstrated that they could create heralded single photons from a CMOS-compatible silicon chip operating at room temperature in the near-infrared; An international team of scientists has developed a tabletop device that produces coherent bursts of shortwavelength radiation.
