Coherent multiphoton photoemission spectroscopy of image-potential state on Ir(111) surface

Multiphoton photoemission provides a means to investigate unoccupied electronic states via nonlinear light-matter interactions. In this work, we employ five-photon photoemission spectroscopy to identify, for the first time, the image-potential state (IPS) on the Ir(111) surface. Distinct from common...
