Ultrafast unbalanced electron distributions in quasicrystalline 30° twisted bilayer graphene
T. Suzuki, T. Iimori, S. J. Ahn +15
Layers of twisted bilayer graphene exhibit varieties of exotic quantum phenomena1-5. Today, the twist angle Θ has become an important degree of freedom for exploring novel states o…
Dirac Electrons in a Dodecagonal Graphene Quasicrystal
Sung Joon Ahn, Pilkyung Moon, Tae-Hoon Kim +10
Quantum states of quasiparticles in solids are dictated by symmetry. Thus, a discovery of unconventional symmetry can provide a new opportunity to reach a novel quantum state. Rece…
Epitaxial Growth of a Single-Crystal Hybridized Boron Nitride and Graphene layer on a Wide-Band Gap Semiconductor
Ha-Chul Shin, Yamujin Jang, Tae-Hoon Kim +11
Vertical and lateral heterogeneous structures of two-dimensional (2D) materials have paved the way for pioneering studies on the physics and applications of 2D materials. A hybridi…
Direct momentum-resolved observation of one-dimensional confinement of externally doped electrons within a single subnanometre-scale wire
Inkyung Song, Dong-Hwa Oh, Ha-Chul Shin +6
Cutting-edge research in the band engineering of nanowires at the ultimate fine scale is related to the minimum scale of a nanowire-based device. The fundamental issue at the subna…
Designed Three-Dimensional Freestanding Single-Crystal Carbon Architectures
Ji-Hoon Park, Dae-Hyun Cho, Youngkwon Moon +6
Single-crystal carbon nanomaterials have led to great advances in nanotechnology. The first single-crystal carbon nanomaterial, fullerene, was fabricated in a zero-dimensional form…
Opening and reversible control of a wide energy gap in uniform monolayer graphene
Cheolho Jeon, Ha-Chul Shin, Inkyung Song +8
For graphene to be used in semiconductor applications, a wide energy gap of at least 0.5 eV at the Dirac energy must be opened without the introduction of atomic defects. However,…
