Electron Spectroscopy

Electron spectroscopy anaylses the electron energies emitted from a sample to provide surface-sensitive chemical and physical information. This section provides further details on the instrumentation available at the ISC.

X-ray Photoelectron Spectroscopy is a surface sensitive technique that effectively probes the chemistry and electronic states by exciting photoelectrons from the sample through incident X-ray radiation. The ISC has the capability of analysing a variety of samples (powders, electrode surfaces etc.) and in different sampling conditions, including UHV, Near Ambiant Pressure (NAP), and quasi-in situ conditions. more
Ultraviolet Photoelectron Spectroscopy (UPS) uses ultraviolet radiation to excite photoelectrons from the sample. The resultant photoelectron energy analysis allows for the determination of molecular orbital energies in the valence region. more
Auger electron spectroscopy (AES) analyses electrons emitted from an excited atom after a series of relaxation events. The emitted electrons provide valuable elemental information from the surface layers of a material. more
Electron Energy Loss Spectroscopy (EELS) measures the inelastically scattered electron from the sample, by comparing the energy loss to the primary incident electron beam. The technique allows for the detail characterisation of exictation vibrations, and/or electronic transitions at the surface, providing valuable chemical and vibrational information. more
