Ultrathin bismuth exhibits promising performance for topological insulators due to its narrow band gap and intrinsic strong spin–orbit coupling, as well as for energy‐related applications because of its electronic and mechanical properties. However, large‐scale production of 2D sheets via liquid‐phase exfoliation as an established large‐scale method is restricted by the strong interaction between...
The transformation of bulk bismuth to ultrahigh‐aspect‐ratio 2D bismuthene microsheets (size: 2 × 2 × 0.002 μm) is described in article number 2002037 by Martin Pumera and co‐workers. This method involves the melting and recrystallization of bismuth under a sonication tip. The microsheets are prepared in water and are stable in an ambient condition for a long time. Overall, this method allows the...
