New Findings on Physics from Technical University of Denmark Summarized

June 17, 2014



By a News Reporter-Staff News Editor at Physics Week -- Current study results on Physics have been published. According to news reporting originating from Kongens Lyngby, Denmark, by VerticalNews correspondents, research stated, "Experimental advances allow for the inclusion of multiple probes to measure the transport properties of a sample surface. We develop a theory of dual-probe scanning tunneling microscopy using a Green's function formalism, and apply it to graphene."

Our news editors obtained a quote from the research from the Technical University of Denmark, "Sampling the local conduction properties at finite length scales yields real space conductance maps which show anisotropy for pristine graphene systems and quantum interference effects in the presence of isolated impurities. Spectral signatures in the Fourier transforms of real space conductance maps include characteristics that can be related to different scattering processes."

According to the news editors, the research concluded: "We compute the conductance maps of graphene systems with different edge geometries or height fluctuations to determine the effects of nonideal graphene samples on dual-probe measurements."
