Nonlinear Breakdown of Antisymmetric Flexoelectric Coupling
Yingzhuo Lun, Yida Yang, Tingjun Wang +4
Flexoelectric coupling is conventionally regarded as antisymmetric, such that reversing the strain gradient reverses the polarization direction while preserving its magnitude. Here…
Low and Anisotropic Thermal Conductivity in Mixed-Valent SnS
Xingang Jiang, Yongheng Li, Weiping Guo +4
Compounds of Sn, such as SnSe and SnS, exhibit novel phonon characteristics and low thermal conductivity, making them emerging star materials in the thermoelectric family. In this…
Polarization Vortices in a Ferromagnetic Metal via Twistronics
Yingzhuo Lun, Xinxin Hu, Qi Ren +15
Recent advances in moire engineering provide new pathways for manipulating lattice distortions and electronic properties in low-dimensional materials. Here, we demonstrate that twi…
Identifying Highly Deformable van der Waals Layered Chalcogenides with Superior Thermoelectric Performance Using Deformability Factors and Interpretable Machine Learning
Qi Ren, Yingzhuo Lun, Bonan Zhu +2
Van der Waals layered chalcogenide-based flexible thermoelectric devices show great potential for applications in wearable electronics. However, materials that are both highly defo…
