Abstract Measuring anisotropic exciton transport in organic crystals goes beyond just assessing one‐dimensional (1D) transport. It offers a deeper understanding of how molecular packing and interactions affect different dimensions. However, achieving nanoscale precision measuring lengths linking them to specific crystalline directions remains formidable challenge. Here the development photoetching method is reported visualize distances as gaps within two‐dimensional (2D) crystals, which turn allows for use scanning electron microscope (SEM) precisely measure sizes. The combined with hetero‐seeded self‐assembly enables conventional fluorescence spectrometry precise determination 2D structures at nanoscale. Relying on this novel method, unexpectedly found that increasing intermolecular one crystal direction not only improves dimension but also enhances other dimension. These findings provide valuable insights engineering materials require efficient across extended distances.

Abstract In semiconductor technology, bandgap engineering is a cornerstone challenge that continues to evolve. By employing the full and low-energy tight-binding model, we focused on effects of twist-angle bandgaps twisted bilayer γ -graphyne graphdiyne. Our results indicated reducing from 21.79 ∘ 0.67 can significantly narrow by as much 0.5 eV. Drawing concept hybridization, this reduction in elucidated average interlayer coupling valence band maximum state conduction minimum state. research presents versatile approach modulation two-dimensional semiconductors.
