The current-voltage (I-U) characteristics we have been measured for thin films of 1-acenaphthenol and 9,10-dimethylanthracene prepared from their commercially available materials as products with purity ≥ 10-3mass %. Using the method of differential processing of the characteristics, charge transport mechanism in these films was assessed.
Spectral grade materials obtained in zone-melting process from commercially available 1-acenaphthenol and 9,10-dimethyl-anthracene were characterized electrically. The layers vaporized in 10-5 Torr vacuum posses high resistivity of the order of 1011 - 1012 Ωm and the concentration of traps lower than 1015cm-3.
The nucleation kinetics of fluoranthene in 1,2-dichloroethane solution from which good quality crystals of that hydrocarbon were previously grown have been studied. Measurements of the metastable zone width (MSZW), represented by the maximum undercooling ((ΔΘmax), which were carried out by means of the density, ultrasonic velocity and transparency techniques, have shown the great influence of the...
