Dimensional Control of Excitonic Interactions in Exfoliated 2D Molecular Crystals
Jonghyun Son, Seonghyun Koo, Daniel Yim +17
Two-dimensional (2D) materials provide unique opportunities to tailor excited-state properties through reduced dimensionality, altered dielectric screening and layer-dependent stru…
Atomic-Scale Tailoring of Chemisorbed Atomic Oxygen on Epitaxial Graphene for Graphene-Based Electronic Devices
Tae Soo Kim, Taemin Ahn, Tae-Hwan Kim +2
Graphene, with its unique band structure, mechanical stability, and high charge mobility, holds great promise for next-generation electronics. Nevertheless, its zero band gap chall…
In-Plane and Out-of-Plane Excitonic Coupling in 2D Molecular Crystals
Dogyeong Kim, Sol Lee, Jiwon Park +4
Understanding the nature of molecular excitons in low-dimensional molecular solids is of paramount importance in fundamental photophysics and various applications such as energy ha…
Pu nuclear magnetic resonance in the candidate topological insulator PuB
A. P. Dioguardi, H. Yasuoka, S. M. Thomas +9
We present a detailed nuclear magnetic resonance (NMR) study of Pu in bulk and powdered single-crystal plutonium tetraboride (PuB), which has recently been investigat…
Broken-Symmetry Quantum Hall States in Twisted Bilayer Graphene
Youngwook Kim, Jaesung Park, Intek Song +8
Twisted bilayer graphene offers a unique bilayer two-dimensional-electron system where the layer separation is only in sub-nanometer scale. Unlike Bernal-stacked bilayer, the layer…
Direct observation of the M2 phase with its Mott transition in a VO film
Hoon Kim, Tetiana V. Slusar, Dirk Wulferding +7
In VO, the explicit origin of the insulator-to-metal transition is still disputable between Peierls and Mott insulators. Along with the controversy, its second monoclinic (M2)…
Spatially resolved penetration depth measurements and vortex manipulation in the ferromagnetic superconductor ErNi2B2C
Dirk Wulferding, Ilkyu Yang, Jinho Yang +6
We present a local probe study of the magnetic superconductor, ErNiBC, using magnetic force microscopy at sub-Kelvin temperatures. ErNiBC is an ideal system to expl…
Breakdown of the interlayer coherence in twisted bilayer graphene
Youngwook Kim, Hoyeol Yun, Seung-Geol Nam +8
Coherent motion of the electrons in the Bloch states is one of the fundamental concepts of the charge conduction in solid state physics. In layered materials, however, such a condi…
