Methane as an effective hydrogen source for single-layer graphene synthesis on Cu foil by plasma enhanced chemical vapor deposition
Yong Seung Kim, Jae Hong Lee, Young Duck Kim +8
A single-layer graphene is synthesized on Cu foil in the absence of H2 flow by plasma enhanced chemical vapor deposition (PECVD). In lieu of an explicit H2 flow, hydrogen species a…

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…
