Band bending at oxide surfaces induced by chemical doping or electric fields is known to create metallic surfaces with properties not found in the bulk, such as high electron mobility, magnetism or superconductivity. In this talk I show that photoexcitation of the ZnO(10-10) surface acts in direct analogy with chemical doping and induces band bending on ultrashort timescales. [more]
