Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The electrophysical properties of thermally deposited thin films of dihydrodibenzotetraaza[14]-annulene were investigated applying ohmic gold electrodes to them. The volt-ampere characteristic of planar thin films symmetric structure Au – dihydrodibenzotetraaza[14]annulene – Au under dark condition was measured. The direct current conductivity in this structure at room temperature and at a small applied voltage was ohmic, carried out by thermally generated carriers, and the conductivity, limited by space charges carried out by the injected carriers, was observed at a higher applied voltage. The transition from ohmic conductivity to conductivity limited by space charges occurred at an electric field strength in a thin film of Е ~ 4 × 10⁴ V/m. |
