The Strength of Mechanically-Exfoliated Monolayer Graphene
Xin Zhao, Dimitrios G. Papageorgiou, Liyan Zhu +2
The deformation and fracture behaviour of one-atom-thick mechanically exfoliated graphene has been studied in detail. Monolayer graphene flakes with different lengths, widths and s…
Monolayer MgC: Negative Poisson's ratio and unconventional 2D emergent fermions
Shan-Shan Wang, Ying Liu, Zhi-Ming Yu +4
Novel two-dimensional (2D) emergent fermions and negative Poisson's ratio in 2D materials are fascinating subjects of research. Here, based on first-principles calculations and the…
Engineering the thermal conductivity along an individual silicon nanowire by selective helium ion irradiation
Yunshan Zhao, Dan Liu, Jie Chen +10
The ability to engineer the thermal conductivity of materials allows us to control the flow of heat and derive novel functionalities such as thermal rectification, thermal switchin…
Blue Phosphorene Oxide: Strain-tunable Quantum Phase Transitions and Novel 2D Emergent Fermions
Liyan Zhu, Shan-Shan Wang, Shan Guan +4
Tunable quantum phase transitions and novel emergent fermions in solid state materials are fascinating subjects of research. Here, we propose a new stable two-dimensional (2D) mate…
Direction dependent thermal conductivity of monolayer phosphorene: parameterization of Stillinger-Weber potential and molecular dynamics study
Wen Xu, Liyan Zhu, Yongqing Cai +2
A Stillinger-Weber interatomic potential is parameterized for phosphorene. It well reproduces the crystal structure, cohesive energy and phonon dispersion predicted by first-princi…
Electronic, Dielectric, and Plasmonic Properties of Two-Dimensional Electride Materials XN (X=Ca, Sr): A First-Principles Study
Shan Guan, Shengyuan A. Yang, Liyan Zhu +2
Based on first-principles calculations, we systematically study the electronic, dielectric, and plasmonic properties of two-dimensional (2D) electride materials XN (X=Ca, Sr).…
Co-existence of size-dependent and size-independent thermal conductivities in single layer black phosphorus
Liyan Zhu, Gang Zhang, Baowen Li
Thermal conductivity of single layer black phosphorus (BP) is investigated by combining density functional calculations and Peierls-Boltzmann transport equation. Differing from iso…
