Near the plasma frequency spatial dispersion is an important effect in metal optics, since it
leads to optical excitation of plasma waves. We outline an extension of local metal optics …

Nonlocal response of the surface to the incident light is included into an ab initio one-step
photoemission theory. Surface-state normal emission spectra from Be (0001) and Al (100) …

In this review article we discuss some new developments in photoemission theories. We first
discuss basic theoretical framework on the basis of quantum electrodynamics (QED), which …

Photoelectron spectra from (100) and (111) surfaces of aluminum in the photon energy
range 44–100 eV are measured and calculated within an ab initio one-step theory …

We demonstrate that in order for hydrodynamic-model calculations to reproduce recent
photoemission yield spectra the parameters must be chosen to ensure the existence of an …

The photoemission cross-section of Shockley states of Cu (111) and Ag (111) surfaces is
studied over a wide range of photon energies. The constant initial-state spectra are very …

The contribution to the absorptance of a semi-infinite metal from electron-hole pair
excitations, in terms of the inverse dielectric function of the metal, is discussed. A simple …

Theoretical predictions for inverse photoemission from free-electron-like materials are tested
by measurement of the energy and angle dependence of the emitted photon intensity from …

Normal-emission spectra from 1T-TiS 2 have been calculated within the one-step model with
explicit consideration of the dielectric response to the incident p-polarized photon field …

The semi-classical infinite barrier (SCIB) model for the calculation of surface electromagnetic
fields in jellium models for metals is extended to handle smooth interfaces. In the extended …
