From: Self-defined dual charge percolation networks for solution-processed multithreshold transistors
Composition-dependent transfer characteristics of the polymer:TpNC heterojunction transistors with a a fixed polymer concentration of 5 mg mL−1 and b a fixed TpNC concentration of 20 mg mL−1. The solid and dotted lines correspond to DCNBT-IDT:TpNC and PMMA:TpNC, respectively. c SEM images of the TpNC and polymer:TpNC heterojunctions (top and middle rows) and the corresponding cross-sections (bottom panel). d Electrical characteristics fitted with Bässler’s model and the percolation-limited model. e Composition-dependent threshold voltages of the intermediate (“1/2”) and on (“1”) states in the heterojunction transistors.
