Materials scientists can control the interlayer twist angle of materials to offer a powerful method to tune electronic properties of two-dimensional (2-D) van der Waals materials. In such materials, the electrical conductivity ...
A sphere and a cube can be deformed into one another without cuts or stitches. A mug and a glass cannot because, to deform the first into the second, the handle needs to be broken. Topology is the branch of mathematics that ...
