Main Effect

Laser-induced fragmentation and desorption of fragments of PTCDA films vacuum-deposited on GaAs (100) substrate has been studied by time-of-flight (TOF) mass spectroscopy. The main effect caused by pulsed laser light irradiation (pulse duration: 10 ns, photon energy: 2.34 eV and laser fluence ranging from 0.5 to 7 mJ/cm2) is PTCDA molecular fragmentation and desorption of the fragments formed, whereas no desorption of intact PTCDA molecule was detected. Fragments formed are perylene core C20H8, its half C10H4, carbon dioxide, carbon monoxide and atomic oxygen. All desorbing fragments have essentially different kinetic energy. The mechanism of photoinduced molecular fragmentation and desorption is discussed.

ABSTRACTA KrF* (248 nm) laser-based process for the deposition of carbon films containing a large fraction of diamond is reported. The experiment consists of focusing the pulsed laser beam at normal incidence onto the surface of a low temperature (20° - 150° C) silicon substrate in the presence of acetic or malonic acid vapor. The process does not require the presence of hydrogen, although an inert buffer gas, e. g. argon, is usually employed. Deposition rates of approximately 1 μm - hour−1 are obtained, and the presence of diamond in the deposited film is inferred from Raman Spectroscopy and Auger Electron Spectroscopy.
