Ultra high vacuum scanning tunneling microscopy to study thin film growth
An ultra high vacuum chamber was constructed to study thin film growth using scanning tunneling microscopy (STM). The sample stage is specially designed so that samples can be transferred in situ among various film preparation ...
Photoelectron spectroscopy of negative cobalt clusters: Correlation of promotion energy to reactivity
Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to ...
