Quantum ricochets: surface capture, release and energy loss of fast ions hitting a polar surface at grazing incidence
(IOP Publishing, 2014-06-09)
A diffraction mechanism is proposed for the capture, multiple bouncing and final escape of a fast ion (keV) impinging on the surface of a polarizable material at grazing incidence. Capture and escape are effected by elastic ...
One-dimensional potential for image-potential states on graphene
(IOP Publishing, 2014-02-05)
In the framework of dielectric theory, the static non-local self-energy of an electron near an ultra-thin polarizable layer has been calculated and applied to study binding energies of image-potential states near free-standing ...
Giant diamagnetism of gold nanorods
(IOP Publishing, 2014-07-30)
The presence of giant diamagnetism in Au nanorods, NRs, is shown to be a possible consequence of field induced currents in the surface electrons. The distance, Delta , between quantum surface energy levels has been calculated ...
