Channels of oxygen diffusion in single crystal rubrene revealed
Robert J. Thompson, Thomas Bennett, Sarah Fearn +5
Electronic devices made from organic materials have the potential to support a more ecologically friendly and affordable future. However, the ability to fabricate devices with well…
Effects of Lower Symmetry and Dimensionality on Raman Spectra in 2D WSe2
Xin Luo, Yanyuan Zhao, Jun Zhang +4
We report the observation and interpretation of new Raman peaks in few-layer tungsten diselenide (WSe2), induced by the reduction of symmetry going from 3D to 2D. In general, Raman…
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…
Lattice dynamics in mono- and few-layer sheets of WS2 and WSe2
Weijie Zhao, Zohreh Ghorannevis, Amara Kiran Kumar +6
Thickness is one of the fundamental parameters that define the electronic, optical, and thermal properties of two-dimensional (2D) crystals. Phonons in molybdenum disulfide (MoS2)…
Observation of an in-plane vortex lattice transition in the multiband superconductor 2H-NbSe2 using scanning tunneling spectroscopy
I. Fridman, C. Kloc, C. Petrovic +1
We report real-space evidence for an in-plane vortex lattice (VL) transition in the multiband superconductor 2H-NbSe2, observed by laterally imaging subsurface vortices with scanni…
Evolution of Electronic Structure in Atomically Thin Sheets of WS2 and WSe2
Weijie Zhao, Zohreh Ghorannevis, Leiqiang Chua +4
Geometrical confinement effect in exfoliated sheets of layered materials leads to significant evolution of energy dispersion with decreasing layer thickness. Molybdenum disulphide…
