Weyl semimetals are a recently discovered class of materials, in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Physics and Technology and Ioffe Institute in St. Petersburg have shown that these materials represent perfect gain media for lasers. The research findings were published in…
Organic Solar Cells Get an Upgrade
An international team of materials scientists from France, Russia, and Kazakhstan found a way to boost the efficiency of organic solar cells several times. The new study, published in the Journal of Materials Chemistry A, has shown that ordered structures based on organic molecules can be used to produce solar power. Solar panels, or batteries,…
Researchers Greenlight Gas Detection at Room Temperature
Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. For the first time, this enables a gas sensor operating at room temperature. The paper was published in the journal Scientific Reports. Multisensor arrays for determining gas mixture composition are currently…
Scientists Revisit Optical Constraints of Ultrathin Gold Films
Researchers at MIPT have conducted highly precise measurements of the optical constants of ultrathin gold films with thicknesses ranging from 20 to 200 billionths of a meter in the optical part of the electromagnetic spectrum. Thin gold films are key components of modern micro- and nanoscale optical and optoelectronic devices. The research findings will be…
