Auger photoelectron coincidence spectroscopy of molecules adsorbed on a gold wire surface

In this paper, we present the results on Auger/photoelectron coincidence spectroscopy (APECS) of molecules—propanethiol and bovine serum albumin (BSA)-deposited on a gold wire surface, using a magnetic bottle electron time-of-flight spectrometer. Although this study is preliminary and conducted unde...

Description
Summary:In this paper, we present the results on Auger/photoelectron coincidence spectroscopy (APECS) of molecules—propanethiol and bovine serum albumin (BSA)-deposited on a gold wire surface, using a magnetic bottle electron time-of-flight spectrometer. Although this study is preliminary and conducted under low vacuum (∼10 −7 mbar) conditions in comparison to surface science standards, it demonstrates the APECS methods high efficiency in probing complex molecules. We also establish its versatility and potential for easy extension to other various systems.
