Optimization of s-Polarization Sensitivity in Apertureless Near-Field Optical Microscopy
Figure 4
SEM images of several ANSOM probes with varying thickness of silver coating. (a) Bare silicon probe with no silver coating, (b) probe with 20 nm silver coating, (c) probe with 40 nm silver coating, and (d) probe with 60 nm silver coating. The zoomed inset shows how we estimate the apex size.
