Monolayers of microspheres are grown by Langmuir–Blodgett technique.
The spheres are made of polystyrene, the substrates are in quartz, BK7 glass, or Si.
The monolayers are covered with a metallic film (Au or Ag) by thermal evaporation.
Long-range arrays of prismatoid metal structures remain after removal of monolayer.
Laser dewetting of such long-range arrays of metal structures is presented and discussed.
