Graphene from the chemical vapor deposition is investigated and characterized to be a continuous and uniform monolayer or fewlayer. LiNbO3 capped by graphene layer show an extraordinary absorption enhancement in an attenuated total reflection (ATR) measurement at a wide bandwidth of 500~4000 cm-1, which can be explained by resonance absorption resulting from the coupling of graphene surface plasmons with optical modes of LiNbO3-SiO2 Fabry-Perot cavity and LiNbO3 planar waveguide. The simulation results are generally consistent with the ATR experimental results. The absorption spectra versus temperature of this plasmonic configuration is also investigated, which show that increasing the testing temperature not only highlights the atomic vibrational peaks of graphene, but also enhances the absorption at several characteristic absorption frequencies due to the enhanced coupling between the surface plamons excitations and the optical modes.Two-dimensional (2D) piezoelectric materials have attracted wide attention because they are of great significance to the composition of piezoelectric nanogenerators. In this work, we have systematically studied the piezoelectric properties of 2D LiAlTe2 by using the first-principles calculation and found the 2D LiAlTe2 monolayer exhibits both large in-plane piezoelectric coefficient d11 (3.73 pmV-1) and out-of-plane piezoelectric coefficient d31 (0.97 pmV-1). Moreover, the piezoelectric coefficients of 2D LiAlTe2 are highly tunable by strain and stacking. When different uniaxial strains are applied, d11 changes dramatically, but d31 changes little. When
