Selective synthesis of large-area monolayer tin sulfide from simple substances
Kazuki Koyama, Jun Ishihara, Takeshi Odagawa +11
Both tin monosulfide (SnS) and tin disulfide (SnS2) are thermodynamically stable layered materials with potential for spin-valleytronic devices and photodetectors. Notably, monolay…

Direct imprinting of arbitrary spin textures using programmable structured light in a semiconductor two-dimensional electron gas
Keito Kikuchi, Jun Ishihara, Miari Hiyama +5
Precise control of spatial spin structures, such as spin helices, is critical for advancing spintronic devices, particularly in non-volatile, low-power information storage and proc…

Enhanced interlayer electron transfer by surface treatments in mixed-dimensional van der Waals semiconductor heterostructures
Takeshi Odagawa, Sota Yamamoto, Chaoliang Zhang +7
We investigate the excitonic species in WS monolayers transferred onto III-V semiconductor substrates with different surface treatments. When the III-V substrates were covere…
