Young PI at CNRS Strasbourg (ICPEES), studying organic electrochemical transistors (OECTs). Member of @STELORG. Active defender of women-men equality in academia.
#MATSUS in Valencia, Spain. What a nice conference focused on the development of next-gen OECTs and understanding of the fundamental mechanisms.
Thank you to @scottkeene.bsky.social, @SabineLudwig, @TomVanDerPol for the organisation and kind invitation 🧠☀️

Figure 5 finally presents how aligned OECTs enhance the stability over 1000 pulsing cycles compared to non-aligned ones. Note that the stability remains the key parameter to enhance. Limiting the (de)doping range enhances stability, reaching 93% of Ids retention, at the expense of Ids amplification.

Figure 4 summarizes the enhancement of the normalized-gm (recalculated from the literature) and µC* values over the years for aqueous-based OECTs, underlining the unprecedented values achieved with aligned PBTTT-8O. A naive sketch tentatively illustrates the key parameters benefiting aligned films.

Figure 3 presents you how correlating the evolution of the absorbance of the channel vs. the Ids current flowing through over 1000 ON/OFF cycles informs us on the mechanisms of degradation. The aligned channels demonstrated faster response and higher cycling stability compared to non-aligned ones.

Figure 2 highlights that the > x10 Ids output enhancement is directly found on the transfer curves (raw data, independent of any model)

Figure 1 shows that aligning the polymer chain along the OECT channel direction does not imapct the electrochemical doping behaviour comapred to non-aligned channel

➡️ Paper out in Adv. Mater. ⬅️ Want to boost the IDS output of an OECT? By aligning the chains of a high-perf' single-ether PBTTT, we reached an unprecedented signal amplification (gmL/Wd = 2 580 S cm-1). Collab:
