This UHV system houses LEED, XPS, UPS, STM , AFM and sample preparation facilities.
The VT AFM XA can be heated up to 650K or cooled using liquid nitrogen/helium to below -40K. Samples are usually:
Running in 2 modes of scanning probe microscopy (SPM) – either atomic force microscopy (AFM) or scanning tunnelling microscopy (STM).
The STM – using an almost atomically-free electrically biased tip samples that conduct electricity, allowing for rastered quasi 3D images to be produced by electron clouds. The AFM uses a tip attached to a cantilever as the probe, scanning across the sample. Typical operating pressures are below 1E-9 mbar. Resolution of 1-5 nm allowing for atomic structure on the surface of the sample to be visible. For larger samples 1-E-6m are possible.
Diamond Light Source is the UK's national synchrotron science facility, located at the Harwell Science and Innovation Campus in Oxfordshire.
