摘　　要：范德瓦耳斯材料凭借独特的结构和优异的性能在应变工程领域引起了广泛的关注.通过改变原子晶格和电子结构,应变可以调控范德瓦耳斯材料的物理性质,最终实现高性能的新原理电子器件.首先总结了诱导原位应变的实验方法,然后通过回顾范德瓦耳斯磁性、超导和拓扑材料在原位应变调控研究的最新进展,以及应变相关的器件应用开发,探讨该领域当前面临的挑战和未来的机遇.Van der Waals(vdW)materials have attracted extensive research interest in the field of strain engineering due to their unique structure and excellent performance.By changing the atomic lattice and electronic structure,strain can modulate the novel physical properties of vdW materials and generate new quantum states,ultimately realize high-performance electronic devices based on new principles.In this paper,we first comprehensively review various experimental strategies of inducing in-situ strain,which include the bending deformation of flexible substrates,mechanical stretching of microelectromechanical systems and electrodeformation of piezoelectric substrates.Then,we outline the recent research progresses of in-situ strain-modulated magnetism,superconductivity and topological properties in vdW materials,as well as the development of strain-related device applications,such as intelligent strain sensors and strain-programmable probabilistic computing.Finally,we examine the current challenges and provide insights into potential opportunities in the field of strain engineering.
