Anisotropic Photostriction and Strain-modulated Carrier Lifetimes in Orthorhombic Semiconductors
Jianxin Yu, Kun Yang, Jiawen Li +3
We demonstrate anisotropic photostriction in two-dimensional orthorhombic semiconductors using time-dependent density functional theory. By tracing the dynamics of photoexcited car…
Photostriction-tunable Polarization and Structural Dynamics in Interlayer Sliding Ferroelectrics
Kun Yang, Jianxin Yu, Jia Zhang +2
Two-dimensional ferroelectrics with robust polarization offer promising opportunities for non-volatile memory, field-effect transistors, and optoelectronic devices. However, the im…
Photostriction Facilitates Relaxation of Lattice Distortion in Two-Dimensional Perovskites
Jin Zhang, Kun Yang, Jianxin Yu +4
The photostriction effect, a light-induced mechanical deformation in materials, originates from the intricate interplay between lattice structure and electronic excitation. In phot…
Photoexcitation-induced Stacking Transition Assisted by Intralayer Reconstruction in Charge-Density-Wave Materials
Jin Zhang, Yang Yang, Jia Zhang +5
Laser excitation has emerged as an effective tool for probing microscopic interactions and manipulating phases of matter. Among charge density wave (CDW) materials, 1T-TaS2 has gar…
