The basic properties of materials can be changed by structuring their volume with various nanoparticles as well as by surface modification. In this study, calcium fluoride (CaF2) is selected as a model matrix for investigating the characteristic surface properties, and its spectral and mechanical properties, as well as the surface wetting of a CaF2 surface modified with carbon nanotubes, are compared with the properties of pure crystals. Laser-oriented deposition and an additional electric field varied in the range of 100–600 V/cm are applied for surface structuring. The experimental results are confirmed by quantum-chemical modeling.
