Intrinsic bending flexoelectric constants in two-dimensional materials
Xiaoying Zhuang, Bo He, Brahmanandam Javvaji +1
Flexoelectricity is a form of electromechanical coupling that has recently emerged because, unlike piezoelectricity, it is theoretically possible in any dielectric material. Two-di…
High flexoelectric constants in Janus transition-metal dichalcogenides
Brahmanandam Javvaji, Bo He, Xiaoying Zhuang +1
Due to their combination of mechanical stiffness and flexibility, two-dimensional (2D) materials have received significant interest as potential electromechanical materials. Flexoe…
Interlayer Breathing and Shear Modes in Few-Layer Black Phosphorus
Jin-Wu Jiang, Bing-Shen Wang, Harold S. Park
The interlayer breathing and shear modes in few-layer black phosphorus are investigated for their symmetry and lattice dynamical properties. The symmetry groups for the even-layer…
A Stillinger-Weber Potential for Single-Layer Black Phosphorus, and the Importance of Cross-Pucker Interactions for Negative Poisson's Ratio and Edge Stress-Induced Bending
Jin-Wu Jiang, Timon Rabczuk, Harold S. Park
The distinguishing structural feature of single-layer black phosphorus is its puckered structure, which leads to many novel physical properties. In this work, we first present a ne…
A Review on Flexural Mode of Graphene: Lattice Dynamics, Thermal Conduction, Thermal Expansion, Elasticity, and Nanomechanical Resonance
Jin-Wu Jiang, Bing-Shen Wang, Jian-Sheng Wang +1
Single-layer graphene is so flexible that its flexural mode (also called the ZA mode, bending mode, or out-of-plane transverse acoustic mode) is important for its thermal and mecha…
Mechanical Properties of MoS2/Graphene Heterostructures
Jin-Wu Jiang, Harold S. Park
We perform classic molecular dynamics simulations to comparatively investigate the mechanical properties of single-layer MoS2 and a graphene/MoS2/graphene heterostructure under uni…
