Technological devices are becoming smaller and more feature-rich in part because scientists are exploring new materials and new ways to use existing materials. One area being investigated by materials scientists is the function of flat two-dimensional (2D) crystals. These crystals are just one molecule thick and can be arranged in layers to create van der Waals heterostructures (vdWs).
“Many interesting phenomena have been seen in 2D vdWs, and new kinds of electronic and optical components have been proposed as a result,” professor Shigeo Maruyama at the University of Tokyo said. “However, we wondered whether it’s possible to create spatially compact one-dimensional (1D) vdWs and what kinds of useful and…READ MORE
