Hopg surface
WebIn this article, authors used STM and STS to study the gas absorption property of Au, Ni and Pt nanoparticles on HOPG surface. Contribution of surface states, lattice distortion and charging is discussed. This is an interesting work and I have a few questions below: 1. STM is a surface measurement and do not show the cross section information.
