A spinel crystal structure exhibits unusual, pressure-induced superconductivity

Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like in so-called high-temperature superconductors, this property emerges at higher temperatures. Researchers at the Center for High Pressure Science & Technology Advanced Research, Chinese Academy of Sciences and other institutes recently observed pressure-induced superconductivity in CuIr2S4, a spinel that typically becomes an insulator when cooled below about 230 K, meaning that electricity can no longer flow through it. Their paper, published in Physical Review Letters, shows that progressively tuning this material's crystal structure using pressure prompts the emergence of two distinct superconducting phases, dubbed SC-I and SC-II, with a maximum transition temperature of 18.2 K.

Spinel-type sulfide semiconductors achieve room-temperature light emission across violet to orange spectrum

A spinel-type sulfide semiconductor that can emit light from violet to orange at room temperature has been developed by researchers at Science Tokyo, overcoming the efficiency limitations of current LED and solar cell materials. The material, (Zn,Mg)Sc2S4, can be chemically tuned to switch between n-type and p-type conduction, leading to future pn homojunction devices. This versatile semiconductor offers a practical path toward the development of more efficient LEDs and solar cells. LEDs, solar cells, and semiconductor lasers rely on pn junctions for their operation, where an electron-rich n-type region meets a hole-rich p-type region. At this junction, electrons and holes either recombine to produce light, as in LEDs, or are separated to generate current, as in solar cells. The efficiency of these processes depends on the material itself. Gallium arsenide (GaAs) recombines carriers efficiently and emits light, making it ideal for LEDs, while silicon excels at capturing sunlight and generating current but is a poor light emitter.
