J. N. OShea et al, Surface Science 486,157 (2001) Summary In-situ UHV electrospray deposition allows us to investigate non-volatile molecules and nanostructures with a suite of surface science techniques. Electron spectroscopy can reveal a great deal about the movement of electrons and the interactions between molecules and surfaces. Acknowledgements Chris Satterley Joachim Schnadt
