Nonlinear Photoluminescence in Atomically Thin Layered WSe2 Arising from Diffusion-Assisted Exciton-Exciton Annihilation
Shinichiro Mouri, Yuhei Miyauchi, Minglin Toh +3
We studied multi-exciton dynamics in monolayer WSe2 using nonlinear photoluminescence (PL) spectroscopy and Monte Carlo simulations. We observed strong nonlinear saturation behavio…
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…
Transport properties of monolayer MoS grown by chemical vapour deposition
Hennrik Schmidt, Shunfeng Wang, Leiqiang Chu +8
Recent success in the growth of monolayer MoS via chemical vapor deposition (CVD) has opened up prospects for the implementation of these materials into thin film electronic an…
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)…
