Experimental realization of graphene-like borophene
Wenbin Li, Longjuan Kong, Caiyun Chen +7
We report a successful preparation of a purely honeycomb, graphene-like borophene, by using an Al(111) surface as the substrate and molecular beam epitaxy (MBE) growth in ultrahigh…
Direct evidences of pentagonal silicon chains and magic clusters
Shaoxiang Sheng, Runze Ma, Jiangbin Wu +11
Pentagon is one of the most beautiful geometric structures in nature, but it is rarely seen simply because five-fold symmetry is mathematically forbidden in a 2D or 3D periodic lat…
Experimental Realization of Two-Dimensional Boron Sheets
Baojie Feng, Jin Zhang, Qing Zhong +7
Boron is the fifth element in the periodic table and possesses rich chemistry second only to carbon. A striking feature of boron is that B12 icosahedral cages occur as the building…
Persistent Dirac Fermion State on Bulk-like Si(111) Surface
Jian Chen, Wenbin Li, Baojie Feng +4
The "multilayer silicene" films were grown on Ag(111), with increasing thickness above 30 monolayers (ML). We found that the "multilayer silicene" is indeed a bulk Si(111) film. Su…
