摘要

Apowerful driving force behind the information and communication technology revolution we have witnessed in the last decades is the ability to control on-demand the electronic properties of a material. The best example is the field-effect transistor, a device whose ability to conduct an electrical current can be extensively qontrolled by applying an electric field. Several hundred million of these devices operate in one pocket, closely packed inside a smartphone. This functionality is made possible by the creation of an interface between two materials, a semiconductor and an insulator, that in their bulk form do not offer useful properties. It is the interface which generates the functionality. An exciting opportunity, opened by recent advances in material science, is to study interfaces and surfaces of quantum materials that even in their bulk exhibit functional properties such as magnetism or superconductivity [1].Indeed, there is great potential for new electronic properties at their interfaces.
