Query: N-, B-, P-, Al-, As-, Ga-graphdiyne/graphyne lattices: First-principles
  investigation of mechanical, optical and electronic properties   Graphdiyne and graphyne are carbon-based two-dimensional (2D) porous atomic
lattices, with outstanding physics and excellent application prospects for
advanced technologies, like nanoelectronics and energy storage systems. During
the last year, B- and N-graphdiyne nanomembranes were experimentally realized.
Motivated by the latest experimental advances, in this work we predicted novel
N-, B-, P-, Al-, As-, Ga-graphdiyne/graphyne 2D lattices. We then conducted
density functional theory simulations to obtain the energy minimized structures
and explore the mechanical, thermal stability, electronic and optical
characteristics of these novel porous nanosheets. Acquired theoretical results
reveal that the predicted carbon-based lattices are thermally stable. It was
moreover found that these novel 2D nanostructures can exhibit remarkably high
tensile strengths or stretchability. The electronic structure analysis reveals
semiconducting electronic character for the predicted monolayers. Moreover, the
optical results indicate that the first absorption peaks of the imaginary part
of the dielectric function for these novel porous lattices along the in-plane
directions are in the visible, IR and near-IR (NIR) range of light. This work
highlights the outstanding properties of graphdiyne/graphyne lattices and
recommends them as promising candidates to design stretchable energy storage
and nanoelectronics systems.
