Abstract

Abstract: We have employed 1, 7-dibromo- N, N' -ditridecyl-3, 4, 9, 10-perylenetetra carboxylic diimide (DB-PTCDI-C13) for the development of novel n-type monolayer field-effect-transistor (FET). Functionalization of PTCDI core with long alkyl chain and bulky bromine atoms improved the solubility and made n-type monolayer FET performance possible via solution deposition processes. Annealing effect of spin coated films and drop casted films have been discussed. Liquid crystalline phase of DB-PTCDI-C13 turned out to be playing an important role in controlling the film quality and mobility. The highest mobility was 5.8 × 10 −3 cm 2 V −1 s −1 after annealing, of which device has been then tested for doping by potassium.
