摘　　要：声表面波是一种在弹性材料表面传播的高度定向机械波,通过压电效应和应变场与材料相互作用,能够实现对准粒子输运、能带结构和电荷自旋等物性的精确调控与探测.近年来,声表面波技术在凝聚态物理前沿研究中崭露头角.本文综述了声表面波技术在凝聚态物理中的应用进展,重点介绍了声波诱导电荷输运、声光伏效应及声波透射探测物性等方面的实验研究成果,并展望了其在凝聚态物理基础研究以及未来声电器件应用方面的前景.Surface acoustic waves(SAWs)are highly directional mechanical waves that propagate along the surface of elastic materials.Through the piezoelectric effect and the interaction of strain fields with the material,they can achieve precise control and detection of properties such as quasi-particle transport,band structure,and charge spin.In recent years,SAWs have emerged as a novel technique in cutting-edge research in condensed matter physics.This article begined with the application of SAW technology in condensed matter physics,focusing on experimental advances in acoustically induced charge transport,photovoltaic effects,and acoustic wave transmission for detection.The prospects of applying SAW technology in condensed matter physics research,as well as potential acoustoelectronic device applications,were also prospected.
