Plasmon triggered ultrafast operation of color centers in hBN layers
Vasilios Karanikolas, Takuya Iwasaki, Joel Henzie +6
High-quality emission centers in two-dimensional materials are promising components for future photonic and optoelectronic applications. Carbon-enriched hexagonal boron nitride (hB…
Electron transport in folded bilayer-bilayer graphene/hexagonal boron nitride superlattices under high magnetic fields
Takuya Iwasaki, Motoi Kimata, Yoshifumi Morita +7
Employing graphene as a template, we fabricate moiré superlattices by stacking bilayer or folded bilayer-bilayer graphene (BLG or fBBLG) and hexagonal boron nitride (hBN), i.e., hB…
Direct growth of germanene at interfaces between van der Waals materials and Ag(111)
Seiya Suzuki, Takuya Iwasaki, K. Kanishka H. De Silva +7
Germanene, a two-dimensional honeycomb germanium crystal, is grown at graphene/Ag(111) and hexagonal boron nitride (h-BN)/Ag(111) interfaces by segregating germanium atoms. A simpl…
Light-Assisted and Gate-Tunable Oxygen Gas Sensor based on Rhenium Disulfide (ReS2) Field-Effect Transistors
Amir Zulkefli, Bablu Mukherjee, Ryoma Hayakawa +3
Gas sensors based on transition metal dichalcogenides (TMDCs) have attracted much attention from a new perspective involving light-assisted or gate-voltage operation. However, thei…
Single-Carrier Transport in Graphene/hBN Superlattices
Takuya Iwasaki, Shu Nakaharai, Yutaka Wakayama +4
Graphene/hexagonal boron nitride (hBN) moiré superlattices have attracted interest for use in the study of many-body effects and fractal physics in Dirac fermion systems. Many exot…
Topological Valley Currents in Bilayer Graphene/Hexagonal Boron Nitride Superlattices
Kosuke Endo, Katsuyoshi Komatsu, Takuya Iwasaki +8
Graphene superlattices have recently been attracting growing interest as an emergent class of quantum metamaterials. In this paper, we report the observation of nonlocal transport…
