An international team of researchers (Germany, Austria, Hungary, UK) succeeded in developing a new type of quantum dots by combining graphene and hexagonal boron nitride, also a single layer of material quite like graphene except that it is insulating. The two layers cannot perfectly match when put one on top of the other resulting in an extremely regular wave-like spatial oscillation of the graphene layer out of the perfect plane. The potential landscape created by the regular superstructure allows for accurately placing the quantum dot, or even moving it continuously and thus smoothly changing its properties… read more.
