The Formation and Transformation of Low‐Dimensional Carbon Nanomaterials by Electron Irradiation
Small, EarlyView.The article reviews irradiation phenomena in graphene‐ or graphite‐based nanomaterials from the scale of single atoms to tens or hundreds of nanometers. Observations dating back to the 1990s can now be explained on the basis of new results. The evolution of the understanding during three decades of research is presented, and the remaining problems are ...

Continuous Strain Modulation of Moiré Superlattice Symmetry From Triangle to Rectangle
Small, EarlyView.Continuous symmetry modulation of the moiré superlattice in the van der Waals heterostructures of atomically thin transition metal dichalcogenides is realized. By fabricating heterostructures on flexible substrate, controllable strain is applied, enabling the intentional distortion of the moiré superlattice.
