Polarization-dependence of palladium deposition on ferroelectric lithium niobate (0001) surfaces
Seungchul Kim, Michael Rutenberg Schoenberg, Andrew M. Rappe
We investigate the effect of ferroelectric polarization direction on the geometric properties of Pd deposited on the positive and negative surfaces of LiNbO (0001). We predict…
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…
Minimal Single-Particle Hamiltonian for Charge Carriers in Epitaxial Graphene on 4H-SiC(0001)
Seungchul Kim, Jisoon Ihm, Hyoung Joon Choi +1
We present a minimal but crucial microscopic theory for epitaxial graphene and graphene nanoribbons on the 4H-SiC(0001) surface -- protopypical materials to explore physical proper…
Monovacancy-induced magnetism in graphene bilayers
Sangkook Choi, Byoung Wook Jeong, Seungchul Kim +1
Vacancy-induced magnetism in graphene bilayers is investigated using spin-polarized density functional theory calculations. One of two graphene layers has a monovacancy. Two atomic…
Origins of anomalous electronic structures of epitaxial graphene on silicon carbide
Seungchul Kim, Jisoon Ihm, Hyoung Joon Choi +1
On the basis of first-principles calculations, we report that a novel interfacial atomic structure occurs between graphene and the surface of silicon carbide, destroying the Dirac…
