Mapping Domain Wall Topology in the Magnetic Weyl Semimetal CeAlSi
Yue Sun, Changmin Lee, Hung-Yu Yang +3
We report full vector mapping of local magnetization in CeAlSi, a Weyl semimetal in which both inversion and time-reversal symmetries are broken. The vector maps reveal unanticipat…
Ultrafast photocarrier recombination dynamics in black phosphorus-molybdenum disulfide (BP/MoS2) heterostructure
Zhonghui Nie, Yuhan Wang, Ziling Li +8
Van der Waals (vdW) heterostructures constructed with two-dimensional (2D) materials have attracted great interests, due to their fascinating properties and potential for novel app…
High-Responsivity Photodetection by Self-Catalyzed Phase-Pure P-GaAs Nanowire
Hassan Ali, Yunyan Zhang, Jing Tang +13
Defects are detrimental for optoelectronics devices, such as stacking faults can form carrier-transportation barriers, and foreign impurities (Au) with deep-energy levels can form…
High-Q microcavity enhanced optical properties of CuInS/ZnS colloidal quantum dots towards non-photodegradation
Yue Sun, Feilong Song, Chenjiang Qian +11
We report on a temporal evolution of photoluminescence (PL) spectroscopy of CuInS/ZnS colloidal quantum dots (QDs) by drop-casting on SiO/Si substrates and high quality…
Gain enhanced Fano resonance in a coupled photonic crystal cavity-waveguide structure
Yanhui Zhao, Chenjiang Qian, Kangsheng Qiu +4
Systems with coupled cavities and waveguides have been demonstrated as optical switches and optical sensors. To optimize the functionalities of these optical devices, Fano resonanc…
Observation of nonlinear thermal optical dynamics in a chalcogenide nanobeam cavity
Yue Sun, Thomas P. White, Duk-Yong Choi +1
We present a theoretical and experimental analysis of nonlinear thermo-optic effects in suspended chalcogenide glass nanobeam cavities. We measure the power dependent resonance pea…
Slow phonon vortices and defect modes in periodic nano-waveguides
Yue Sun, Anton S. Desyatnikov, Andrey A. Sukhorukov
We identify a broad class of phonon modes with persistent vortex fluxes at arbitrarily slow propagating velocities in periodic nano-waveguides. Such phonon vortices are associated…

Mingkai Liu, Yue Sun, David A. Powell +4
We propose and verify experimentally a new concept for achieving strong nonlinear coupling between the electromagnetic and elastic properties in metamaterials. This coupling is pro…
Slow-light enhanced optical forces between longitudinally shifted photonic-crystal nanowire waveguides
Yue Sun, Thomas P. White, Andrey A. Sukhorukov
We reveal that slow-light enhanced optical forces between side-coupled photonic-crystal nanowire waveguides can be flexibly controlled by introducing a relative longitudinal shift.…
