Scanning probe microscope STM system

KTH wants to purchase a bolt-on Scanning Tunnelling Microscope (STM) system which will be added to an ultrahigh vacuum (UHV) surface science instrument.

Purpose of procurement

The aim of the tender:

KTH wants to purchase a bolt-on Scanning Tunnelling Microscope system (hereafter called STM system) which will be added to an ultrahigh vacuum (UHV) surface science instrument. The STM system will be part of a molecular beam surface scattering instrument being built to investigate the effects of reactant gas pressure on the behaviour of catalytic surfaces. As the changes induced in the surface by the reactant gasses are dynamic, experiments must be performed at elevated pressure. The ability to measure STM images at both UHV and the elevated pressures and temperatures at which catalytic reactions occur is therefore particularly important.
