“…Singh et al made an n‐type memory device based on PCBM with a PVA gate dielectric 95. A large reverse of the V GS resulted in a large metastable hysteresis in the transfer characteristics with a retention time of 15 h and a writing time of 500 s. Similar devices have also been obtained using by p‐type OFETs based on nonperipherally substituted octahexyl lead phthalocyanine 96. A similar hysteresis phenomenon was also observed using deoxyribonucleic acid (DNA) biopolymers as the gate dielectric 97, 98…”

Functional organic field-effect transistors (OFETs) have attracted increasing attention in the past few years due to their wide variety of potential applications. Research on functional OFETs underpins future advances in organic electronics. In this review, different types of functional OFETs including organic phototransistors, organic memory FETs, organic light emitting FETs, sensors based on OFETs and other functional OFETs are introduced. In order to provide a comprehensive overview of this field, the history, current status of research, main challenges and prospects for functional OFETs are all discussed.

“…Poly(vinyl alcohol) (PVA) is one of the best polymers that provide TOMDs with low‐voltage and high‐retention characteristics at room temperature 33–37. However, the memory characteristics of the TOMDs with the PVA memory layers were found to almost completely disappear upon exposing them to high‐temperature conditions (>85 °C).…”

It is demonstrated that a heme protein (cytochrome c [Cyt c]) nanosphere plays a strong anchoring role in binding hydroxyl groups of poly(vinyl alcohol) (PVA) leading to outstanding high‐temperature (100 °C) retention characteristics of transistor‐type organic memory devices (TOMDs). The PVA:Cyt c layers are spin‐coated on indium tin oxide gate electrodes from aqueous solutions with various Cyt c contents up to 50 wt%, followed by the formation of poly(3‐hexylthiophene) (P3HT) channel layers and nickel/aluminum top source/drain electrodes in TOMDs. Results show that adding 20 wt% Cyt c improves the drain current of devices in the presence of good hysteresis characteristics, which are maintained even after exposure to high‐temperature conditions (100 °C). The excellent conservation of hysteresis characteristics is attributed to the formation of Cyt c nanospheres that act as an anchoring point to retard the relaxation of PVA chains via specific interactions (hydrogen bonding etc.) between amino groups in the Cyt c nanosphere surfaces and hydroxyl groups in the PVA chains. The optimized PVA:Cyt c layers (20 wt% Cyt c, thermal treatment at 100 °C) deliver excellent retention characteristics to TOMDs, whereas no memory function is measured in the case of the pristine PVA layers at 100 °C.
