Brillouin scattering of light is now shown to attenuate the Brownian motion of microscopic acoustic resonators. This electrostrictive phenomenon could be a useful complement to the ponderomotive and ...

本文突破性地揭示了中心对称半导体Si基pn结中由内置电场诱导对称性破缺产生的新型压电电子学效应（Piezotronic Effect）。通过电致伸缩效应（electrostriction）实现应变介电调控，在负微分电阻区获得高达753的应变灵敏度（GF），远超传统硅基传感器。研究为拓展压 ...

Researchers have discovered a new way to engineer thin films that change volume under an electric field. Their technique could help scientists create small, energy-efficient biomedical devices (Nature ...
