Edge-Driven Phase Transitions in 2D Ice
Suchit Negi, Alexandra Carvalho, Maxim Trushin +1
2D water, confined by atomically flat layered materials, may transit into various crystalline phases even at room temperature. However, to gain full control over the crystalline st…
Two-dimensional non-linear hydrodynamics and nanofluidics
Maxim Trushin, Alexandra Carvalho, A. H. Castro Neto
A water monolayer squeezed between two solid planes experiences strong out-of-plane confinement effects while expanding freely within the plane. As a consequence, the transport of…
Evidence of Spin Frustration in Vanadium Diselenide Monolayer Magnet
Ping Kwan Johnny Wong, Wen Zhang, Fabio Bussolotti +22
Monolayer VSe2, featuring both charge density wave and magnetism phenomena, represents a unique van der Waals magnet in the family of metallic two-dimensional transition-metal dich…
A general approach for the synthesis of two-dimensional binary compounds
Abhay Shivayogimath, Joachim Dahl Thomsen, David M. A. Mackenzie +7
Only a few of the vast range of potential two-dimensional materials have been isolated or synthesised to date. Typically, 2D materials are discovered by mechanically exfoliating na…
Edge phonons in black phosphorus
H. B. Ribeiro, C. E. P. Villegas, D. A. Bahamon +6
Exfoliated black phosphorus has recently emerged as a new two-dimensional crystal that, due to its peculiar and anisotropic crystalline and electronic band structures, may have pot…
Magnetic effects in sulfur-decorated graphene
Choongyu Hwang, Shane A. Cybart, S. J. Shin +13
The interaction between two different materials can present novel phenomena that are quite different from the physical properties observed when each material stands alone. Strong e…
Tunable room-temperature ferromagnet using an iron-oxide and graphene oxide nanocomposite
Aigu L. Lin, J. N. B. Rodrigues, Chenliang Su +7
Magnetic materials have found wide application ranging from electronics and memories to medicine. Essential to these advances is the control of the magnetic order. To date, most ro…
Direct dry transfer of chemical vapor deposition graphene to polymeric substrates
Guilhermino J. M. Fechine, Inigo Martin-Fernandez, George Yiapanis +5
We demonstrate the direct dry transfer of large area Chemical Vapor Deposition graphene to several polymers (low density polyethylene, high density polyethylene, polystyrene, polyl…
Van der Waals forces and electron-electron interactions in two strained graphene layers
Anand Sharma, Peter Harnish, Alexander Sylvester +2
We evaluate the van der Waals (vdW) interaction energy at zero temperature between two undoped strained graphene layers separated by a finite distance. We consider the following th…
Photocarrier relaxation in two-dimensional semiconductors
Daichi Kozawa, Rajeev Kumar, Alexandra Carvalho +8
Two-dimensional (2D) crystals of semiconducting transition metal dichalcogenides (TMD) absorb a large fraction of incident photons in the visible frequencies despite being atomical…
Origin of indirect optical transitions in few-layer MoS2, WS2 and WSe2
Weijie Zhao, R. M. Ribeiro, Minglin Toh +4
It has been well established that single layer MX2 (M=Mo,W and X=S,Se) are direct gap semiconductors with band edges coinciding at the K point in contrast to their indirect gap mul…
Band nesting and the optical response of two-dimensional semiconducting transition metal dichalcogenides
A. Carvalho, R. M. Ribeiro, A. H. Castro Neto
We have studied the optical conductivity of two-dimensional (2D) semiconducting transition metal dichalcogenides (STMDC) using ab-initio density functional theory (DFT). We find th…
Silicon Layer Intercalation of Centimeter-Scale, Epitaxially-Grown Monolayer Graphene on Ru(0001)
Jinhai Mao, Li Huang, Yi Pan +13
We develop a strategy for graphene growth on Ru(0001) followed by silicon-layer intercalation that not only weakens the interaction of graphene with the metal substrate but also re…
