Autor: M. A. Zabolotnyi, N. G. Kuvshinskii, N. A. Davidenko, Alexander A. Ishchenko, N. P. Borolina

Publikováno v: High Energy Chemistry. 38:13-20

Field dependences of photogeneration quantum yields of charge carriers in films of amorphous molecular semiconductors at high external electric field strengths cannot be always explained in terms of the Onsager or the Poole–Frenkel model, which do

Unusual temperature dependences of the photoconductivity and recombination luminescence of amorphous molecular semiconductors doped with ionic dyes

Autor: Yu. A. Skryshevskii, Alexander A. Ishchenko, N. I. Ostapenko, N. G. Kuvshinskii, N. A. Davidenko, Andrey Kadashchuk

Publikováno v: Scopus-Elsevier

A nonexponential increase in photoconductivity with increasing temperature is discovered for poly(N-epoxypropylcarbazole) (PEPK) films doped with polymethine dyes. It is postulated that traps for nonequilibrium charge carriers form in these films dur

Effect of an electric field on the dissociation of electron-hole pairs interacting with triplet excitons in amorphous molecular semiconductors

Autor: N. G. Kuvshinskii, N. A. Davidenko

Publikováno v: Physics of the Solid State. 39:916-919

The photoconductivity of amorphous molecular semiconductor films increases with the simultaneous photogeneration of singlet electron-hole pairs (EHPs) and triplet excitons but decreases when singlet EHPs are replaced by triplet EHPs. As the electric

Publikováno v: Polymer Mechanics. 11:958-960

Some properties of polymers used for the thermoplastic recording of information are discussed and experimental data on the region of non-Newtonian and Newtonian flow in a polymer are presented. A Bingham body can thus be selected as a mathematical mo
