Abstract

In present study four newly synthesized organic semiconductor compounds have been used for fabrication of the planar
metal / organic semiconductor / metal structures. I-V characteristics of the samples were investigated. Effect of the
hysteresis of the I-V characteristics was observed for all samples investigated. However, strength of the hysteresis depended
on organic semiconductor used. Charge transfer mechanisms were considered. In all cases the main charge transfer
mechanism was trap activated tunneling. Yet at higher electric fields Schottky emission should be considered as well.
