## Title

    on Ir(111) surface

## Description

- description: "Multiphoton photoemission provides a means to investigate unoccupied
    electronic states via nonlinear light-matter interactions.\r\nIn this work, we
    employ five-photon photoemission spectroscopy to identify, for the first time,
    the image-potential state (IPS) on the Ir(111) surface.\r\nDistinct from commonly
    studied noble metals such as Cu and Ag, Ir(111) electronic structure leads to
    a strong sensitivity to excitation energy:\r\na reduction from 1.57-1.49 eV significantly
    diminishes the signal.\r\nThe theoretical analysis attributes this effect to the
    d-band proximity to the Fermi level, which influences the initial-state population
    and transition probabilities governing the multiphoton excitation pathways."
