“…With the advent in spectra of the components of the substrate material the signal of light particles increases many times. The main contribution of the mass m / z = 28 and m / z = 44 fragments make the CO and CO2 molecules of carbonyl group of PTCDA and NTCDA, which is consistent with the results of [1,5].…”

In this paper we present an experimental study of migration of atoms and molecules of the substrate material in the thickness of the film in the direction of the surface by means of laser desorption mass spectrometry. The method is based on the time-of-flight principle of particle detection, desorbed from the sample surface by a laser pulse (LP) of nanosecond duration [. The main advantage of TOF mass spectrometer is that the registration of product desorption is carried out at the site of direct flight from the sample to the ion source, i. e. in the mass spectrum does not participate particle, reflected from the walls and other elements. In addition, the method allows to measure the time delay of the particles emission, relative to the exciting laser irradiation [.

“…4, curves 1 and 2). The study of irradiated areas of the films by atomic force microscopy [5] showed that in these areas, the laser pulse with energy density of 24 mJ/cm 2 per pulse formed open sections of the substrate surface. It is through them desorption of arsenic atoms and molecules when use the irradiation of first harmonic occurs.…”

“…Laser annealing is a promising method for improving the morphology of films. Irradiation of the surface of the films with laser radiation in the absorption region leads to the alignment and cleaning of the outer layer [3]. Under the action of laser radiation, fragmentation of organic films and desorption of fragments from the surface occur [4].…”

The paper presents the results of mass spectrometric studies of laser-stimulated desorption from the surface of thin films based on organic copper phthalocyanine molecules with peripheral substituents on gallium arsenide substrates. Thin films (30-80 nm) of copper phthalocyanine with peripheral substituents in this regard are studied for the first time. The composition of particles desorbed from the surface of CuPc and CuPcF16 films by laser radiation of various wavelengths of 532 nm and 1.06 μm with a pulse duration of 10 ns was studied. The identification of the main fragments of molecules present in the desorption stream was carried out. It was shown that under the action of laser radiation, the surface is leveled and the films are fragmented, followed by desorption of molecular fragments.
