Which of the following is applicable to thin film?

Step-by-step solution

Nanostructures are classified based on the number of dimensions that are not confined to the nanoscale range ( Zero-dimensional (0D) nanostructures have all three dimensions in the nanoscale (e.g., quantum dots, nanoparticles). One-dimensional (1D) nanostructures have two dimensions in the nanoscale and one extended dimension (e.g., nanowires, nanotubes). Two-dimensional (2D) nanostructures have one dimension in the nanoscale (thickness) and two extended dimensions (length and width). A thin film falls under this c
