New kinds of ‘superlattices’ could lead to improvements in electronics, from transistors to LEDs. A research team led by UCLA scientists and engineers has developed a method to make new kinds of artificial “superlattices” – materials composed of alternating layers of ultra-thin “2D” sheets, which are only one or a few atoms thick...
