An international team of researchers (Switzerland, Japan) combined tungsten diselenide with molybdenum diselenide to reveal new properties with an array of possible high-tech. By using a laser to generate light beams and slightly shifting the positions of the two 2D materials to create a moiré pattern, they were able to use excitons to change and regulate the polarization, wavelength and intensity of light. By manipulating the “valley,” of the exiciton, it can be leveraged to code and process information at a nanoscopic level. Linking several devices that incorporate this technology would give us a new way to process data. The research is a step towards the manipulation of the valley degree of freedom in realistic device applications. This can lead to a new generation of electronic devices with transistors that undergo less energy loss and heat dissipation…read more. TECHNICAL ARTICLEÂ
