Planar and van der Waals heterostructures for vertical tunnelling single electron transistors
Gwangwoo Kim, Sung-Soo Kim, Jonghyuk Jeon +18
Despite a rich choice of two-dimensional materials, which exists these days, heterostructures, both vertical (van der Waals) and in-plane, offer an unprecedented control over the p…
Random telegraph noise in metallic single-walled carbon nanotubes
Hyun-Jong Chung, Tae Woo Uhm, Sung Won Kim +5
We have investigated random telegraph noise (RTN) observed in individual metallic carbon nanotubes (CNTs). Mean lifetimes in high- and low-current states, shigh and slow, have been…
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…
