Fig. 5From: Estimation of the Number of Quantum Dots Immobilized on an Ultra-flat Au SurfaceAFM images of QDs on the dot patterns. The designed dot sizes were 50 nm (a), 100 nm (b), and 500 nm (c). Immobilized QDs are indicated with white arrows in a. d Number density of QDs on the dot patterns. Dashed line represents the number density of QDs on the Au surface without pattern Back to article page
