Entropy-driven electron density and effective model Hamiltonian for boron systems
Chang-Chun He, Shao-Gang Xu, Yu-Jun Zhao +2
The unique electron deficiency of boron makes it challenging to determine the stable structures, leading to a wide variety of forms. In this work, we introduce a statistical model…
Straight nodal-line phonons in symmorphic space groups
Guang Liu, Yuanjun Jin, Zhongjia Chen +1
Based on first-principles calculations and effective model analysis, all possible straight nodal-line phonons in symmorphic space groups are uncovered. A classification of two-band…
Recipe for Dirac Phonon States with Quantized Valley Berry Phase in Two Dimensional Hexagonal Lattices
Yuanjun Jin, Rui Wang, Hu Xu
The topological quantum states in two-dimensional (2D) materials are fascinating subjects of research, which usually highlight electron-related systems. In this work, we present a…
Insights into the Unusual Semiconducting Behavior in Low-Dimensional Boron
Shao-Gang Xu, Xiao-Tian Li, Yu-Jun Zhao +5
Elementary semiconductors are rare and attractive, especially for low-dimensional materials. Unfortunately, most of boron nanostructures were found to be metallic, despite of their…
Two-Dimensional Semiconducting Boron Monolayers
Shao-Gang Xu, Xiao-Tian Li, Yu-Jun Zhao +3
The two-dimensional boron monolayers were reported to be metallic both in previous theoretical predictions and experimental observations, however, we have firstly found a family of…
