Band gap opening by two-dimensional manifestation of Peierls instability in graphene
Sung-Hoon Lee, Hyun-Jong Chung, Jinseong Heo +4
Using first-principles calculations of graphene having high-symmetry distortion or defects, we investigate band gap opening by chiral symmetry breaking, or intervalley mixing, in g…

Pseudospin rotation and valley mixing in electron scattering at graphene edges
Changwon Park, Heejun Yang, Andrew J. Mayne +5
In graphene, the pseudospin and the valley flavor arise as new types of quantum degrees of freedom due to the honeycomb lattice comprising two sublattices (A and B) and two inequiv…
