SUMMARY:Local electronic properties of graphene
DESCRIPTION:Featuring Brian LeRoy\, Arizona State University\nHosted by: An
	tonio Castro Neto\n\nPart of the Biophysics/Condensed Matter Seminar Series
	.\n\nAbstract:  Combining scanning probe microscopy with electrical transpo
	rt measurements is a powerful approach to probe low-dimensional systems. Th
	e local information provided by scanning probe microscopy is invaluable for
	 studying effects such as electron-electron interactions and scattering.  U
	sing scanning tunneling microscopy\, we have probed the local electronic pr
	operties of graphene with atomic resolution.  We studied the effect of ripp
	les\, charged impurities and defects on the local density of states.  We fi
	nd that long-range scattering from ripples and impurities shifts the Dirac 
	point leading to the formation of electron and hole puddles.  Short-range s
	cattering from lattice defects is peaked near the Fermi energy and mixes th
	e two sublattices of graphene.
