Direct Measurement of Exciton Dispersion in the Long-Wavelength Limit
Peiyi He, Jiade Li, Jiakai Wang +15
Exciton dispersion, which governs the propagation, scattering and radiative decay of electron-hole pairs, is essential to optoelectronics and quantum materials. In two-dimensional…
Strain-dependent resistance and giant gauge factor in monolayer WSe2
Mao-Sen Qin, Xing-Guo Ye, Peng-Fei Zhu +4
We report the strong dependence of resistance on uniaxial strain in monolayer WSe2 at various temperatures, where the gauge factor can reach as large as 2400. The observation of st…
Dynamics of Polar Skyrmion Bubbles under Electric Fields
Ruixue Zhu, Zhexin Jiang, Xinxin Zhang +18
Room-temperature polar skyrmion bubbles that are recently found in oxide superlattice, have received enormous interests for their potential applications in nanoelectronics due to t…
Doping Induced Second Harmonic Generation in Centrosymmetric Graphene from Quadrupole Response
Yu Zhang, Di Huang, Yuwei Shan +8
For centrosymmetric materials such as monolayer graphene, no optical second harmonic generation (SHG) is generally expected because it is forbidden under the electric-dipole approx…
Band Structure Engineering of Interfacial Semiconductors Based on Atomically Thin Lead Iodide Crystals
Yan Sun, Zhen Huang, Zishu Zhou +20
To explore new constituents in two-dimensional materials and to combine their best in van der Waals heterostructures, are in great demand as being unique platform to discover new p…
Gate tunable third-order nonlinear optical response of massless Dirac fermions in graphene
Tao Jiang, Di Huang, Jinluo Cheng +13
Materials with massless Dirac fermions can possess exceptionally strong and widely tunable optical nonlinearities. Experiments on graphene monolayer have indeed found very large th…
Evolution of Interlayer Coupling in Twisted MoS2 Bilayers
Kaihui Liu, Liming Zhang, Ting Cao +7
Van der Waals (vdW) coupling is emerging as a powerful method to engineer and tailor physical properties of atomically thin two-dimensional (2D) materials. In graphene/graphene and…
Systematic Determination of Absolute Absorption Cross-section of Individual Carbon Nanotubes
Kaihui Liu, Xiaoping Hong, Sangkook Choi +9
Determination of optical absorption cross-section is always among the central importance of understanding a material. However its realization on individual nanostructures, such as…
High-throughput Imaging and Spectroscopy of Individual Carbon Nanotubes in Devices with Light Microscopy
Kaihui Liu, Xiaoping Hong, Qin Zhou +7
Two paramount challenges in carbon nanotube research are achieving chirality-controlled synthesis and understanding chirality-dependent device physics. High-throughput and in-situ…
