Electronic topological transition in sliding bilayer graphene
Young-Woo Son, Seon-Myeong Choi, Yoon Pyo Hong +2
We demonstrate theoretically that the topology of energy bands and Fermi surface in bilayer graphene undergoes a very sensitive transition when extremely tiny lateral interlayer sh…
Controlling Half-Metallicity of Graphene Nanoribbons by Using a Ferroelectric Polymer
Yea-Lee Lee, Seungchul Kim, Changwon Park +2
On the basis of first-principles computational approaches, we present a new method to drive zigzag graphene nanoribons (ZGNRs) into the half-metallic state using a ferroelectric ma…
Controlling Energy Gap of Bilayer Graphene by Strain
Seon-Myeong Choi, Seung-Hoon Jhi, Young-Woo Son
Using the first principles calculations, we show that mechanically tunable electronic energy gap is realizable in bilayer graphene if different homogeneous strains are applied to t…
