Application of the method of quantum-mechanical calculations allowed the determination of the reorganization energy of the molecules of tetracene and p-quaterphenyl and the estimation of the transfer rate integral between neighbouring molecules present in the solid state. Comparison of the transfer rates for holes with the values of the mobility, obtained experimentally for the polycrystalline tetracene...
We present a calculation method for elimination of the effect of the RC constant of the measuring circuit in the time-of-flight (TOF) measurements where a pulse generation of the photocurrent in a thin layer of low-molecular organic material is exploited. Presented method allows to eliminate the influence of the component of displacement current related to dielectric losses and obtaining the actual...
For the first time the investigations of drift mobility for hole and electron for quasi - amorphous tetracene films were carried out. The quasi -amorphous tetracene films were obtained with the aid of vacuum evaporation technique. Tetracene was deposited on the glass substrates with the temperature 170- 200 K in vacuum of the order of 10-5 Torr. The carrier mobility was evaluated with the aid of the...
