Qualitative Study of the Injection mechanism in N,N'-ditridecyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-C13) based Vertical Organic Field-Effect Transistors

We were interested from a qualitative point of view, to the mechanisms of charge injection in Vertical Organic Field Effect Transistor structures (VOFETs) with n-type organic material (N,N'-ditridecyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-C13)). We developed structures based on perforated electrodes whose nature were varied: Gold/ITO/Silver. We were also able to qualitatively analyze the quality of the interface between the metal and the semiconductor material using a displacement current measurement technique.
