Surface physics can be roughly defined as the study of physical interactions that occur at interfaces.  It overlaps with surface chemistry. Some of the topics investigated in surface physics include [[friction]], [[surface states]], [[surface diffusion]], [[surface reconstruction]], surface [[phonons]] and [[plasmons]], [[epitaxy]], the emission and [[Quantum tunneling|tunneling]] of electrons, [[spintronics]], and the self-assembly of [[nanostructure]]s on surfaces. Techniques to investigate processes at surfaces include [[surface X-ray scattering]], [[scanning probe microscopy]], [[surface-enhanced Raman spectroscopy]] and [[X-ray photoelectron spectroscopy]].
