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…
Magnetic Dirac Fermions and Chern Insulator Supported on Pristine Silicon Surface
Huixia Fu, Zheng Liu, Chao Lian +4
Emergence of ferromagnetism in non-magnetic semiconductors is strongly desirable, especially in topological materials thanks to the possibility to achieve quantum anomalous Hall ef…
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…
Observation of Dirac cone warping and chirality effects in silicene
Baojie Feng, Hui Li, Cheng-Cheng Liu +6
We performed low temperature scanning tunneling microscopy (STM) and spectroscopy (STS) studies on the electronic properties of (R3xR3)R30° phase of silicene on Ag(111) surface. We…
Spontaneous Symmetry Breaking and Dynamic Phase Transition in Monolayer Silicene
Lan Chen, Hui Li, Baojie Feng +5
The (r3xr3)R30° honeycomb of silicene monolayer on Ag(111) was found to undergo a phase transition to two types of mirror-symmetric boundary-separated rhombic phases at temperature…
