Pinaceae Pine Resins (Black Pine, Shore Pine, Rosin, and Baltic Amber) as Natural Dielectrics for Low Operating Voltage, Hysteresis‐Free, Organic Field Effect Transistors

Abstract

Four pinaceae pine resins analyzed in this study: black pine, shore pine, Baltic amber, and rosin demonstrate excellent dielectric properties, outstanding film forming, and ease of processability from ethyl alcohol solutions. Their trap‐free nature allows fabrication of virtually hysteresis‐free organic field effect transistors operating in a low voltage window with excellent stability under bias stress. Such green constituents represent an excellent choice of materials for applications targeting biocompatibility and biodegradability of electronics and sensors, within the overall effort of sustainable electronics development and environmental friendliness.

Industrial vat orange dyes for organic field effect transistors

“…The aluminum gate electrodes (80 nm thick) were subsequently anodized for all the OFET devices fabricated in this study, by growing the aluminum oxide electrochemically via a previously reported recipe 75 that was optimized over the years in our laboratories. 42,76,77 The aluminum used for evaporation of the gate electrode had a purity of 99.999% (ChemPUR GmbH) and each gate electrode was evaporated at a rate of ∼4–5 nm s −1 . The anodization voltage of this study was set to 10 V, producing an aluminum oxide layer of ∼16–17 nm in thickness.…”

Amplifying the dielectric constant of shellac by incorporating natural clays for organic field effect transistors (OFETs)

“…The gate electrode width of 2 mm represents the width of the semiconductor channel, as the schematic in Figure 5 shows. For the calculation of each of the two semiconductors field effect mobility, the specific capacitance of the dielectric (expressed in nF/cm 2 ) was employed in the mobility formula [ 71 , 72 ], by dividing the capacitance measured on the MIM structure of the OFETs slide (see Figure 5 ) to the area of the two overlapping electrodes, i.e. 0.8 mm 2 .…”

Multifunctional Poly(3,4-ethylenedioxythiophene)/Crystalline Nanofibrous Cellulose Composites for Eco-Friendly and Sustainable Electronics

“…These contaminants also penetrate water and soil, entering aquatic environments and threating biodiversity in ecosystems . To meet the criteria of being both “green” and “sustainable”: the future electronics should be flexible, low-cost, biocompatible, biodegradable, recyclable, mechanically durable, and electrically conductive for desired applications. − Along this direction, cellulose materials constitute promising resources for next-generation electronics due to their abundance, renewability, processability, controllable biodegradability, lightweightness, flexibility, and mechanical performance. − …”
