Intervalley scattering of graphene massless Dirac fermions at 3-periodic grain boundaries

22 Oct 2016 Rodrigues J. N. B.

We study how low-energy charge carriers scatter off periodic and linear graphene grain boundaries oriented along the zigzag direction with a periodicity three times greater than that of pristine graphene. These defects map the two Dirac points into the same position, and thus allow for intervalley scattering to occur... (read more)
