Validation of Electrostrictive Performance of P(VDF‐TrFE‐CFE) for kHz Range Applications

Journal of Polymer Science, EarlyView.
This study demonstrates that the high‐frequency deformation of the relaxor ferroelectric polymer P(VDF–TrFE–CFE) is governed by Maxwell's electrostriction, confirming its suitability for fast electromechanical applications. Combining original high‐frequency mechanical characterization, laser vibrometry measurements, and numerical modeling, a ...

Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.
