• ], photopolymerisation [6] and near-field ablation [3][10][11] have been performed. It was found that the material of the triangles plays a distinct role [9], as do the triangles' edge length and height [3][8][10][11] and the material of the underlying substrate [12]. Additionally, nano-particles and nano-particle

To allow calibration of the deposition rate, a movable quartz crystal monitor can be placed at exactly the substrate position. More

• details on the PLD apparatus, including its UHV chamber, are given in [22][23]. By monitoring the deposition rate as a function of the laser power, an ablation threshold of 2.5 J/cm2 was determined for Pt. Standard deposition was performed at 5 J/cm2 resulting in a Pt deposition rate of 1 nm/min. Standard
