Cryogen-free ARPES and High-Resolution XPS Apparatus Spectroscopy X-ray Photoelectron Spectroscope
This is an Angle Resolved PhotoElectron Spectroscopy (ARPES) apparatus, equipped with both ultraviolet (UV) and x-ray sources. It is equipped with a 2D detector electron analyser which allows both the energies and momenta of emitted electrons from the valence band to be measured. This then gives the electronic band dispersion in crystalline solids. The equipment capabilities are:
(a) Ultra-high vacuum, <= 2 x 10E-10 mbar.
(b) Combined energy resolution (electron analyser and UV source) of the system at UV energies is 3 meV.
