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…
Growth of Large Domain Epitaxial Graphene on the C-Face of SiC
Rui Zhang, Yunliang Dong, Wenjie Kong +5
Growth of epitaxial graphene on the C-face of SiC has been investigated. Using a confinement controlled sublimation (CCS) method, we have achieved well controlled growth and been a…
Robust optical emission polarization in MoS2 monolayers through selective valley excitation
G. Sallen, L. Bouet, X. Marie +8
We report polarization resolved photoluminescence from monolayer MoS2, a two-dimensional, non-centrosymmetric crystal with direct energy gaps at two different valleys in momentum s…
