(a) Top view scanning electron micrograph of the nanostructured sample AMO C7. The pillar diameter is 200 nm and the pillar height 337 nm, respectively. (b) Tilted angle view of (a). It is visible that the pillars are cone shaped. (c) Chemical structure of BTAH. In addition length scales are added, which are used in the calculation for the amount being detected in the laser-spot area.
