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…
Giant Piezoelectricity in Monolayer Group IV Monochalcogenides: SnSe, SnS, GeSe and GeS
Ruixiang Fei, Wenbin Li, Ju Li +1
We predict enormous piezoelectric effects in intrinsic monolayer group IV monochalcogenides (MX, M=Sn or Ge, X=Se or S), including SnSe, SnS, GeSe and GeS. Using first-principle si…
Piezoelectricity in Two-Dimensional Group III Monochalcogenides
Wenbin Li, Ju Li
We find that several layer-phase group-III monochalcogenides, including GaS, GaSe and InSe, are piezoelectric in the monolayer form. First-principles calculations reveal that the p…
Deformation-Driven Diffusion and Plastic Flow in Two-Dimensional Amorphous Granular Pillars
Wenbin Li, Jennifer M. Rieser, Andrea J. Liu +2
We report a combined experimental and simulation study of deformation-induced diffusion in compacted two-dimensional amorphous granular pillars, in which thermal fluctuations play…
