Ultrafast generation and decay of a surface metal
Metallization by photoexcitation of defect excitons is observed on very long time scales in bulk semiconductors, while ultrafast control of the conduction properties is appealing. Here, the authors demonstrate the ultrafast (20 fs) generation of a metal at the surface of ZnO upon photoexcitation.
