The nanoprobe comprises 4 individual STMs guided by a high resolution Gemini FEGSEM. By guiding the four STM tips with the SEM it is possible to form reversible, non-destructive electrical contacts to an individual nanostructure. The presence of four tips enables a variety of measurements to be performed including:

Two and Four probe measurements on nanowires/nanotubes
Gated two probe measurements using a third tip as a moveable gate electrode
4 probe Van Der Pauw sheet resistance measurements on nanoscale sheet-like structures (eg. Graphene flakes).

It has a liquid Helium flow cryostat allowing measurements to be taken from 25-450 K.
