Synthesis of metalloborophene nanoribbons on Cu(110)
Xiao-Ji Weng, Yi Zhu, Ying Xu +5
Metalloborophene, characterized by the presence of metal-centered boron wheels denoted as M\c{opyright}Bn, has garnered considerable attention in recent years due to its versatile…
Depositing boron on Cu(111): Borophene or boride?
Xiao-Ji Weng, Jie Bai, Jingyu Hou +7
Large-area single-crystal surface structures were successfully prepared on Cu(111) substrate with boron deposition, which is critical for prospective applications. However, the pro…
Novel boron nitride polymorphs with graphite-diamond hybrid structure
Kun Luo, Baozhong Li, Lei Sun +7
Both boron nitride (BN) and carbon (C) have sp, sp2 and sp3 hybridization modes, and thus resulting in a variety of BN and C polymorphs with similar structures, such as hexagonal B…
Superconductivity in graphite-diamond hybrid
Yanfeng Ge, Kun Luo, Yong Liu +8
Search for new high-temperature superconductors and insight into their superconducting mechanism are of fundamental importance in condensed matter physics. The discovery of near-ro…
Narrow-gap Semiconducting Superhard Amorphous Carbon with Superior Toughness
Shuangshuang Zhang, Yingju Wu, Kun Luo +18
New carbon forms exhibiting extraordinary physico-chemical properties can be generated from nanostructured precursors under extreme pressure. Nevertheless, synthesis of such fascin…
Discovery of carbon-based strongest and hardest amorphous material
Shuangshuang Zhang, Zihe Li, Kun Luo +22
Carbon is likely the most fascinating element of the periodic table because of the diversity of its allotropes stemming from its variable (sp, sp2, and sp3) bonding motifs. Explora…
Direct Observation of Room-Temperature Dislocation Plasticity in Diamond
Anmin Nie, Yeqiang Bu, Junquan Huang +10
It is well known that diamond does not deform plastically at room temperature and usually fails in catastrophic brittle fracture. Here we demonstrate room-temperature dislocation p…
Formation of copper boride on Cu(111)
Chengguang Yue, Xiao-Ji Weng, Guoying Gao +9
Boron forms compounds with nearly all metals, with notable exception of copper and other group IB and IIB elements. Here, we report an unexpected discovery of ordered copper boride…
Temperature-dependent hardness of diamond-structured covalent materials
Xing Feng, Jianwei Xiao, Bin Wen +4
Understanding temperature-dependent hardness of covalent materials is not only of fundamental scientific interest, but also of crucial importance for technical applications. In thi…
Two-dimensional boron on Pb (110) surface
Xin-Ling He, Xiao-Ji Weng, Yue Zhang +7
We simulate boron on Pb(110) surface by using ab initio evolutionary methodology. Interestingly, the two-dimensional (2D) Dirac Pmmn boron can be formed because of good lattice mat…
Coexistence of multiple metastable polytypes in rhombohedral bismuth
Yu Shu, Wentao Hu, Zhongyuan Liu +7
Derivative structural polytypes coexisting with the rhombohedral A7 structure of elemental bismuth (Bi) have been discovered at ambient condition, based on microstructure analyses…
Universal phase transitions of B1 structured stoichiometric transition-metal carbides
Zhisheng Zhao, Xiang-Feng Zhou, Li-Min Wang +5
The high-pressure phase transitions of B1-structured stoichiometric transition metal carbides (TMCs, TM=Ti, Zr, Hf, V, Nb, and Ta) were systematically investigated using ab initio…
