From: Optical visualization of ultrathin mica flakes on semitransparent gold substrates
Reflection optical microscopy, AFM topography, and conduction images of mica flakes on semitransparent gold. (a) Reflection optical microscopy image of a staircase mica flake with thicknesses in the 37- to 277-nm range on a semitransparent gold layer. (b) AFM topography and (c) conduction images of the same area. (d) Topographic and (e) current profiles along the lines indicated in (b) and (c), respectively.
