Probing Interface of Perovskite Oxide Using Surface-specific Terahertz Spectroscopy
Yudan Su, Jiaming Le, Junying Ma +4
The surface/interface species in perovskite oxides play an essential role in many novel emergent physical phenomena and chemical processes. With low eigen-energy in the terahertz r…
Low-frequency Phonon at Perovskite Oxide Interface Studied by Surface-specific Nonlinear Terahertz Spectroscopy
Jiaming Le, Yudan Su, Junying Ma +4
The low-frequency collective excitations, which often occur in the terahertz or multi-terahertz spectral region, play an essential role in many novel emergent phenomena. Despite nu…
Study of Thermal Expansion Coefficients of 2D Materials via Raman Micro-spectroscopy: Revisited
Qianchi Feng, Dongshan Wei, Yudan Su +3
We report a joint study, using Raman micro-spectroscopy and molecular dynamics simulations, on the substrate effect on thermal properties of 2D materials and revisit measurement of…
Mapping Dynamical Magnetic Responses of Ultra-thin Micron-size Superconducting Films using Nitrogen-vacancy Centers in Diamond
Ying Xu, Yijun Yu, Yuen Yung Hui +6
Two-dimensional superconductors have attracted growing interest because of their scientific novelty, structural tunability, and useful properties. Studies of their magnetic respons…
Mechanism of Electric Power Generation from Ionic Droplet Motion on Polymer Supported Graphene
Shanshan Yang, Yudan Su, Ying Xu +9
Graphene-based electric power generation that converts mechanical energy of flow of ionic droplets over the device surface into electricity has emerged as promising candidate for a…
