Ben back from the University of Arkansas

Ben has just returned from visiting Prof. Gregory Salamo and Dr. Michael Hawkridge at the Arkansas Nano-Bio Materials Characterization Facility, University of Arkansas, Fayetteville, USA.


He made use of their X-ray Photoelectron Spectroscopy (XPS) equipment, which provided information about the atomic composition of his films with approx 10 µm resolution (X-Y) and sub-10nm resolution (Z). The XPS experiments allowed him to characterise any chemical changes that may take place in his film to result in the changes in conductivity observed.

Ben travelled to the US with Dr. Loren Picco, a colleague in the Nanophysics group in Bristol, and the trip was funded by an EPSRC “Building Global Engagements” grant. Loren specialises in high-speed AFM (HSAFM) and was visiting Arkansas to help them set up a high-speed AFM to be based in the Nano-Bio Materials Characterization Facility
