Localization and interaction of interlayer excitons in MoSe/WSe heterobilayers
Hanlin Fang, Qiaoling Lin, Yi Zhang +6
Transition metal dichalcogenide (TMD) heterobilayers provide a versatile platform to explore unique excitonic physics via properties of the constituent TMDs and external stimuli. I…
Spatially indirect intervalley excitons in bilayer WSe2
Zhiheng Huang, Yanchong Zhao, Tao Bo +16
Spatially indirect excitons with displaced wavefunctions of electrons and holes play a pivotal role in a large portfolio of fascinating physical phenomena and emerging optoelectron…
Optically and magnetically addressable valley pseudospin of interlayer excitons in bilayer MoS2
Yanchong Zhao, Luojun Du, Shiqi Yang +13
Interlayer valley excitons in bilayer MoS2 feature concurrently large oscillator strength and long lifetime, and hence represent an advantageous scenario for valleytronic applicati…
Engineering symmetry breaking in two-dimensional layered materials
Luojun Du, Tawfique Hasan, Andres Castellanos-Gomez +4
Symmetry breaking in two-dimensional layered materials plays a significant role in their macroscopic electrical, optical, magnetic and topological properties, including but not lim…
Lattice dynamics, phonon chirality and spin-phonon coupling in 2D itinerant ferromagnet Fe3GeTe2
Luojun Du, Jian Tang, Yanchong Zhao +13
Fe3GeTe2 has emerged as one of the most fascinating van der Waals crystals due to its two-dimensional (2D) itinerant ferromagnetism, topological nodal lines and Kondo lattice behav…
Ultra-strong nonlinear optical processes and trigonal warping in MoS layers
A. Säynätjoki, L. Karvonen, H. Rostami +11
We report ultra-strong high-order nonlinear multiphoton processes in monolayer MoS (1L-MoS): the third harmonic is thirty times stronger than the second harmonic, and the f…
Controlling Sub-nm Gaps in Plasmonic Dimers using Graphene
Jan Mertens, Anna L. Eiden, Daniel O. Sigle +9
Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold substrate. This creates a robust, repeatable, and stable sub-nanometre gap for massive plasmo…
1.5 GHz Pulse Generation From a Monolithic Waveguide Laser With a Graphene-Film Saturable Output Coupler
R. Mary, S. J. Beecher, G. Brown +9
We fabricate a saturable absorber mirror by coating a graphene film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode pumped linear cavi…
Tm-doped fiber laser mode-locked by graphene-polymer composite
M. Zhang, E. J. R. Kelleher, F. Torrisi +7
We demonstrate mode-locking of a thulium-doped fiber laser operating at 1.94μm, using a graphene-based saturable absorber. The laser outputs 3.6ps pulses, with~0.4nJ energy and an…
