Ultrafast switching dynamics of the ferroelectric order in stacking-engineered ferroelectrics
Ri He, Bingwen Zhang, Hua Wang +4
The recently discovered ferroelectricity of van der Waals bilayers offers an unconventional route to improve the performance of devices. Key parameters such as switching field and…
Large-scale Atomistic Simulation of Quantum Effects in SrTiO from First Principles
Hongyu Wu, Ri He, Yi Lu +1
Quantum effects of lattice vibration play a major role in many physical properties of condensed matter systems, including thermal properties such as specific heat, structural phase…
Large-scale atomistic simulation of dislocation core structure in face-centered cubic metal with Deep Potential method
Fenglin Deng, Hongyu Wu, Ri He +2
The core structure of dislocations is critical to their mobility, cross slip, and other plastic behaviors. Atomistic simulation of the core structure is limited by the size of firs…
Origin of negative thermal expansion and pressure induced amorphization in zirconium tungstate from machine-learning potential
Ri He, Hongyu Wu, Yi Lu +1
Understanding various macroscopic pressure-volume-temperature properties of materials on the atomistic level has always been an ambition for physicists and material scientists. Par…
Structural Phase Transitions in SrTiO3 from Deep Potential Molecular Dynamics
Ri He, Hongyu Wu, Linfeng Zhang +4
Strontium titanate (SrTiO3) is regarded as an essential material for oxide electronics. One of its many remarkable features is subtle structural phase transition, driven by antifer…
