Photoelectron spectroscopy of transition metal oxide interfaces

Attosecond photoelectron spectroscopy of metal surfaces.

Recent attosecond-streaking spectroscopy experiments [A. L. Cavalieri, Nature (London) 449, 1029 (2007)10.1038/nature06229] using copropagating extreme ultraviolet (XUV) and infrared (IR) pulses of variable relative delay have measured a delay of approximately 100 attoseconds between photoelectrons emitted by a single XUV photon from localized core states and delocalized conduction-band states ...

Understanding Oxide-metal Interfaces

One of the most important features of the interface between an oxide and a metal is the sharp change in dielectric constant between the two materials. This suggests that the stabilisation of charges (lattice ions and defect centres) in the non-metal by the polarisation of the metal may contribute strongly to the interfacial adhesion. This effect can be treated in classical electrostatics by the...

Photoelectron Spectroscopy of Alkali Metal Cluster Anions

ABSTRACf. We present the photoelectron (photodetacment) spectra of K2:-19 recorded using 2.540 eV photons. These spectra are highly structured, providing a wealth of information about the electronic structure of alkali metal clusters, including adiabatic electron affinities and electronic spliuings for each size. Spectral assignments have been made with guidance from theory. For the smaller clu...
