Název v původním jazyce

Charge transient and electrochemical measurements as a tool for characterization and degradation study of organic semiconductors - PMPSis and MEH-PPV

Popis výsledku v původním jazyce

This contribution deals with application of several techniques based on charge transient contactless measurements (isothermal charge transient spectroscopy - IQTS), and by electrochemical methods (double step voltcoulometry - DSVCM and cyclic voltammetry), two complementary methods, which are potentially suitable for obtaining information about bulk relaxation and transport processes and the structure of electronic localized states and their basic parameters. Both methods were tested on two well known polymers, the first, Poly[methylphenylsilylene] and the second Poly[p-phenylene vinylene]. The results were explained both in terms of bulk relaxation ant transport processes, trap parameters and the influence of UV degradation. The metastability in reconstruction of dangling bonds ensuing after the UV degradation due to the Si-Si ? conjugated bond scission and its ability to reconstruct after the thermal anneal was again found in accord with the previous results.
