Název v původním jazyce

Thermally stimulated desorption from the surface of black aluminum layers prepared by PVD methods

Popis výsledku v původním jazyce

The surface exchange interactions between the ambient environment and thin layers of black aluminum prepared by different methods are described. These properties are convenient for materials that are suitable for the fabrication of active layers of chemiresistors. The layers were prepared by magnetron sputtering at room temperature and liquid nitrogen temperature, and evaporation with different compositions and gas flow rates. In this work, the process of thermally stimulated desorption was measured using mass spectrometry. The calculation of the activation energy Eact for the release of individual desorbing atoms, or radicals, from the surface of black aluminum was performed. Knowing of the temperature and the number of particles released by desorption allows us to get an idea of the number of defects and the functionalized structure of the surface layer.
