Photochemical reaction on graphene surfaces controlled by substrate-surface modification with polar self-assembled monolayers
Ryo Nouchi, Kei-ichiro Ikeda
The unique thinness of two-dimensional materials enables control over chemical phenomena at their surfaces by means of various gating techniques. For example, gating methods based…
Staircase-like transfer characteristics in multilayer MoS2 field-effect transistors
Takuya Ohoka, Ryo Nouchi
Layered semiconductors, such as MoS2, have attracted interest as channel materials for post-silicon and beyond-CMOS electronics. Much attention has been devoted to the monolayer li…
Gate-controlled photo-oxidation of graphene for electronic structure modification
Ryo Nouchi, Morihiro Matsumoto, Nobuhiko Mitoma
Graphene is an ultrathin material, which allows us to control surface phenomena by means of field-effect gating. Among various surface phenomena, photo-oxidation is known to be a f…
Edge-induced Schottky barrier modulation at metal contacts to exfoliated molybdenum disulfide flakes
Ryo Nouchi
Ultrathin two-dimensional semiconductors obtained from layered transition-metal dichalcogenides such as molybdenum disulfide (MoS2) are promising for ultimately scaled transistors…
Substituent-Controlled Reversible Switching of Charge-Injection-Barrier Heights at Metal/Organic-Semiconductor Contacts Modified with Disordered Molecular Monolayers
Ryo Nouchi, Takaaki Tanimoto
Electrically stimulated switching of a charge injection barrier at the interface between an organic semiconductor and an electrode modified with a disordered monolayer (DM) is stud…
Competitive interfacial charge transfer to graphene from the electrode contacts and surface adsorbates
Ryo Nouchi, Katsumi Tanigaki
Charge transfer (CT) at metal-graphene contacts induces a potential variation from the contact edges that extends to ~1 micrometer. Potential variations with a similar length shoul…
