Natural Dielectrics for Organic Field Effect Transistors: A Study of Resins from Larch, Spruce and Atlas Cedar Pinaceae Trees

Abstract

Three pinaceae resins originating from trees of high industrial significance: European larch, European spruce, and Atlas cedar that were examined in this work exhibit exceptional film formation, great dielectric qualities, and ease of processing from ethyl alcohol solutions. Because their film surface is essentially trap-free, it is possible to fabricate organic field effect transistors that are hysteresis-free and have outstanding stability under bias stress at working voltages below 10 V. These environmentally friendly materials, which are available at no cost, are a great option for applications aiming to produce sustainable electronics.
