Two-dimensional Excitonic Photoluminescence in Graphene on Cu surface
Youngsin Park, Yoo S. Kim, Chang Woo Myung +10
Despite having outstanding electrical properties, graphene is unsuitable for optical devices because of its zero band gap. Here, we report two-dimensional excitonic photoluminescen…
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…
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,…
Influence of graphene-substrate interactions on configurations of organic molecules on graphene: pentacene/epitaxial graphene/SiC
W. Jung, D. -H. Oh, I. Song +5
Pentacene has been used widely in organic devices, and the interface structure between pentacene and a substrate is known to significantly influence device performances. Here we de…
