Gated resistors with copper phthalocyanine films

The material science offers more and more candidate materials to be applied in the industry of the electronic compounds. Unfortunately, many of them possess high toxicity for humans. Other are expensive or do not meet the technical expectations. This paper is focused on the copper phthalocyanine (CuPc) as a potential compound of low toxicity, electronic components. The synthesis of the CuPc dispersion is presented. By dip-coating this organic compound is deposited onto a ITO covered glass with a compatible insulator. The technology tries to find a transistor behaviour. The electrical tests show an intermediate component behaviour - a gated resistor. The average Source-Drain resistance is 22 G Omega, the positive gate voltage reduces the drain current. The gated resistor function is fulfilled.
