Particle size dependence. Theoretical attainable resolution for amorphous Au particles (top panel) and crystalline Au particles (bottom panel) of different sizes: 20 nm (green), 10 nm (blue), 5 nm (purple) and 2.5 nm (black). Amorphous and crystalline Au are identical for resolutions greater than approximately 5 Å, where the required TIPF is linearly proportional to particle size. Below atomic resolution the required TIPF becomes independent of size for amorphous particles. |
