Paper Abstract

We report the obtaining of thin organic films based on poly(methyl methacrylate) polymer by Pulsed Laser Deposition on silicon substrates and quartz slides. The films were characterized by complementary techniques: x-ray Diffraction, x-ray Photoelectron Spectroscopy, Atomic Force Microscopy, Optical Microscopy, Raman Spectroscopy and Fourier Transform Infrared Spectroscopy. The obtained structures are amorphous. The film composition and structure depend on both the laser fluence as well as on the temperature of the substrate during deposition. We put in evidence in freshly deposited films the presence of diamond-like carbon while its amount strongly increases by annealing at ~400°C in Argon atmosphere.
