Image of the week

Poly(vyniledene fluoride – co – trifluoro ethylene) P(VDF-TrFE) laser induced periodic surface structures (LIPSS).

The AFM image shows the 3D projected height profile of a ferroelectric polymer nanostructure prepared by laser irradiation. In order to overcome the low light absorption of the P(VDF-TrFE) we followed a bilayer approach. Onto this surface it was possible to write and read binary bits of information. A complete description of this project can be found here.
