The Growth of Carbon Based Materials by Supersonic Beam Epitaxy: Experiments, Theory and Calculations

abstract

Characterization of the epitaxial grown material by experimental techniques, (XPS, UPS, Auger, LEED, TEM, and Raman after the collision) demonstrates the potentiality to grow nanostructured materials at room temperature. I also show that, in out-of-equilibrium conditions, ab-initio methods based on the Born-Oppenheimer approximation fail to capture the excited-state dynamics. Hence, we analyse the Si-and Cu-C60 collision in a non-adiabatic nuclear dynamics framework, where stochastic hops occur between adiabatic surfaces, calculated by a time-dependent density functional theory. The description of C60 impacts on metallic and semiconductor substrates is in good agreement with our experimental findings.
