SUMMARY:Relativistic Quantum Physics at Your Pencil Tips: Dirac Fermion in 
	Graphitic Carbon
DESCRIPTION:Featuring Philip Kim\, Columbia University\nHosted by: Antonio 
	Castro Neto\n\nPart of the Physics Department Colloquia Series.\n\nThe mass
	less Dirac particle moving at the speed of light has been a fascinating sub
	ject in relativistic quantum physics. Graphene\, an isolated single atomic 
	layer of graphite\, now provides us an opportunity to investigate such exot
	ic effect in low-energy condensed matter systems. The unique electronic ban
	d structure of graphene lattice provides a linear dispersion relation where
	 the Fermi velocity replaces the role of the speed of light in usual Dirac 
	Fermion spectrum. In this presentation I will discuss experimental conseque
	nce of Dirac Fermion spectrum in charge transport\, realized in two represe
	ntative low dimensional graphitic carbon systems: 1-dimensional carbon nano
	tubes and 2-dimensional graphene. Combined with semiconductor device fabric
	ation techniques and the development of new methods of nanoscaled material 
	synthesis/manipulation enables us to investigate mesoscopic transport pheno
	mena in these materials. The exotic quantum transport behavior discovered i
	n these materials\, such as room temperature ballistic transport\, unusual 
	half-integer quantum Hall effect\, and a non-zero Berry's phase in magneto-
	oscillations will be discussed in the connection to Dirac Fermion descripti
	on in graphitic systems.
