Query: Probing the Synthesis of Two-Dimensional Boron by First-Principles
  Computations   Boron synthesis, in theory: Although two-dimensional boron sheets have
attracted considerable interest because of their theoretically predicted
properties, synthesis of such sheets remains a challenge. The feasibility of
different synthetic methods for two-dimensional boron sheets was assessed using
first-principles calculations, possibly paving the way towards its application
in nanoelectronics.
