BOGDAN DIACONESCU is an academic who published a paper in 2012 entitled Low-energy electron reflectivity from graphene. BOGDAN DIACONESCU published this work as part of a team: Feenstra, Randall. Here is a description of this work: Low,,energy reflectivity of electrons from single, and multi-layer graphene is examined both theoretically and experimentally. A series of minima in the reflectivity over the energy range of 0 â€" 8 eV are found, with the number of minima depending on the number of graphene layers. Using first-principles computations, it is demonstrated that a free standing n-layer graphene slab produces and ï€1 reflectivity minima. This same result is also found experimentally for graphene supported on SiO2. For graphene bonded onto other substrates it is argued that a similar series of reflectivity minima is expected, although in certain cases an additional minimum occurs, at an energy that depends on the graphene-substrate separation and the effective potential in that space..
