Substitutional VSn nanodispersed in MoS film for Pt-scalable catalyst
Frederick Osei-Tutu Agyapong-Fordjour, Seok Joon Yun, Hyung-Jin Kim +10
Among transition metal dichalcogenides (TMdCs) as alternatives for Pt-based catalysts, metallic-TMdCs catalysts have highly reactive basal-plane but are unstable. Meanwhile, chemic…
Band restructuring of ordered/disordered blue TiO2 for visible photocatalyst
Simgeon Oh, Ji-Hee Kim, Hee Min Hwang +6
Black TiO2 with/without noble metal has been proposed for visible photocatalyst, still leaving poor catalyst efficiency. Alternatively, phase-mixed TiO2 such as anatase and rutile…
Gate modulation of the long-range magnetic order in a vanadium-doped WSe2 semiconductor
Dinh Loc Duong, Seong-Gon Kim, Young Hee Lee
We demonstrate the gate-tunability of the long-range magnetic order in a p-type V-doped WSe2 monolayer using ab initio calculations. We found that at a low V-doping concentration l…
Gate tunable optical absorption and band structure of twisted bilayer graphene
Kwangnam Yu, Van Luan Nguyen, Tae Soo Kim +5
We report the infrared transmission measurement on electrically gated twisted bilayer graphene. The optical absorption spectrum clearly manifests the dramatic changes such as the s…
Voltage Scaling of Graphene Device on SrTiO3 Epitaxial Thin Film
Jeongmin Park, Haeyong Kang, Kyeong Tae Kang +4
Electrical transport in monolayer graphene on SrTiO3 (STO) thin film is examined in order to promote gate-voltage scaling using a high-k dielectric material. The atomically flat su…
Controlled Growth of ZnO Nanowire, Nanowall, and Hybrid Nanostructures on Graphene for Piezoelectric Nanogenerators
Brijesh Kumar, Keun Young Lee, Hyun-Kyu Park +3
Precise control of morphologies of one-dimensional (1D) or 2D nanostructures during growth has not been easily accessible, usually degrading the device performance and therefore li…
