“…Bilayer dielectrics in OTFTs can consist of either organic (low- k )/organic (high- k ) or organic/inorganic combinations. 180 Low- k organic polymer insulators offer smooth surfaces and reduced trap levels, facilitating efficient carrier transport and curtailing leakage currents at the interface. The low surface energy of low- k organic polymers improves the microstructure and morphology of deposited OSCs.…”

“…Over many years, OSC materials, as well as OTFT device architectures, have been investigated, and their applications have been significantly explored in several review articles [13][14][15][16][17][18][19][20][21][22]. The geometry of the four most common OTFTs are (1) bottom-gate, bottomcontact; (2) bottom-gate, top-contact (BGTC); (3) top-gate, bottom-contact; and (4) top-gate, topcontact.…”

2,8-Difluoro-5,11-bis(triethylsilylethynyl)anthradithiophene (dif-TES-ADT) is a small molecule organic semiconductor that has drawn much interest as an active channel in Organic Thin Film Transistors (OTFTs). In particular, the solubility of dif-TES-ADT in numerous solvents and amorphous polymers, its chemical stability, and its ease in processing make it a supreme candidate for high performance devices. This review summarizes the progress in material crystallization and the film formation approach, including the surface treatment of Source/Drain metal electrodes with various self-assembled monolayers (SAMs) and the works on vertical phase segregation derived from blending dif-TES-ADT with various polymers. Electrical and environmental stabilities in dif-TES-ADT-based OTFTs and their origins are summarized. Finally, a discussion on the emerging applications of dif-TES-ADT OTFTs is explored. We believe that the individual effort summarized in this work will shed light on optimizing the electrical performance of dif-TES-ADT-based transistors and reveal their potential qualities, which will be useful to their applications in next-generation high performance organic electronics.

Organic–inorganic hybrid dielectric nanomaterials are vital for OTFT applications due to their unique combination of organic dielectric and inorganic properties. Despite the challenges in preparing stable titania (TiO2) nanoparticles, we successfully synthesized colloidally stable organic–inorganic (O-I) TiO2 hybrid nanoparticles using an amphiphilic polymer as a stabilizer through a low-temperature sol–gel process. The resulting O-I TiO2 hybrid sols exhibited long-term stability and formed a high-quality dielectric layer with a high dielectric constant (κ) and minimal leakage current density. We also addressed the effect of the ethylene oxide chain within the hydrophilic segment of the amphiphilic polymer on the dielectric properties of the coating film derived from O-I TiO2 hybrid sols. Using the O-I TiO2 hybrid dielectric layer with excellent insulating properties enhanced the electrical performance of the gate dielectrics, including superior field-effect mobility and stable operation in OTFT devices. We believe that this study provides a reliable method for the preparation of O-I hybrid TiO2 dielectric materials designed to enhance the operational stability and electrical performance of OTFTs.
