Deployable Nanoelectromechanical Bound States in the Continuum Enabled by GHz Lamb Wave Phononic Crystals on LiNbO3 Thin Films
Sheng-Nan Liang, Zhen-Hui Qin, Shu-Mao Wu +3
Bound states in the continuum (BICs) are a fascinating class of eigenstates that trap energy within the continuum, enabling breakthroughs in ultra-low-threshold lasing, high-Q sens…
Generation of spatiotemporal acoustic vortices with arbitrarily oriented orbital angular momentum
Shuai Liu, Hao Ge, Xiang-Yuan Xu +4
Despite extensive exploration of acoustic vortices carrying orbital angular momentum (OAM), the generation of acoustic vortices with OAM orientations beyond the conventional longit…
Double-layer Thin-film LiNbO3 Longitudinally Excited Shear Wave Resonators with Ultra-large Electromechanical Coupling Coefficient and Spurious-Free Performance
Zhen-Hui Qin, Shu-Mao Wu, Chen-Bei Hao +4
This work proposes a double-layer thin-film lithium niobate (LiNbO3) longitudinally excited shear wave resonator with a theoretical electromechanical coupling coefficient exceeding…
Acoustic topological insulator and robust one-way sound transport
Cheng He, Xu Ni, Hao Ge +6
Discovery of novel topological orders of condensed matters is of a significant interest in both fundamental and applied physics due to the associated quantum conductance behaviors…
