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…

Non-monotonic temperature dependent transport in graphene grown by Chemical Vapor Deposition
J. Heo, H. J. Chung, Sung-Hoon Lee +7
Temperature-dependent resistivity of graphene grown by chemical vapor deposition (CVD) is investigated. We observe in low mobility CVD graphene device a strong insulating behavior…
