Paper Abstract

We have fabricated organic complementary inverter comprised of p-channel copper phthalocyanine(CuPc) and n-channel hexadecafluoro phthalocyanine (F16CuPc) based organic thin film transistors (OTFTs) with single Cu metal electrode for both type of OTFTs. The work function of Cu is nearly equal to the highest occupied molecular orbital (HOMO) of CuPc and lowest unoccupied molecular orbital (LUMO) of F16CuPc hence it can be used as source/drain electrode for both type of OTFTs which shows field effect mobilities of CuPc and F16CuPc based OTFTs are 1.27x10-3cm2V-1S-1 and 3.30x10-4cm2V- 1S-1 respectively. Voltage transfer characteristics of complementary inverter show high noise margins and switching voltage around VDD/2 with a maximum gain in the order of 20.
