WebMar 13, 2024 · By characterizing the OECT performance of P3MEEMT transistors as a function of the anion, we find that large hydrophobic anions lower the threshold voltage. We find that, compared to poly (3-hexylthiophene-2,5-diyl) (P3HT), P3MEEMT has faster anion injection rates, which we attribute to the hydration of the P3MEEMT crystal lattice. WebMay 11, 2024 · P3HT films were aligned by high-T rubbing at 186 °C. A highly oriented semicrystalline structure made of alternating crystalline lamellae and amorphous zones is thus obtained with a total lamellar periodicity of 28 nm. [ 31, 32] The lamellae are made of a majority of face-on crystals with some edge-on domains.
