“…Meanwhile, the problem of comparatively low density and poor order exist in reported electrostatic methods. On the other hand, the ability to use printing process to generate NPs arrays has potential benefits of flexibility, simplified manufacturing and efficient use of materials 77, 78. Developing a facile fabrication method to obtain printable Au NPs charge trapping layer with ultrahigh density and uniform size distribution is necessary for technological applications.…”

Flexible non-volatile memories have attracted tremendous attentions for data storage for future electronics application. From device perspective, the advantages of flexible memory devices include thin, lightweight, printable, foldable and stretchable. The flash memories, resistive random access memories (RRAM) and ferroelectric random access memory/ferroelectric field-effect transistor memories (FeRAM/FeFET) are considered as promising candidates for next generation non-volatile memory device. Here, we review the general background knowledge on device structure, working principle, materials, challenges and recent progress with the emphasis on the flexibility of above three categories of non-volatile memories.

“…A very widely employed organic semiconductor in inkjet‐printing is a soluble pentacene derivative, namely, 6,13‐bis(triisopropylsilylethynyl) pentacene (TIPS‐pentacene). Semiconducting inks are prepared by dissolving a few percentages in weight of the molecule into organic solvents such as tetralin, toluene, anisole, and 1,2‐dichlorobenzene ( o ‐DCB) . Depending on the inkjet‐printing conditions, the solvent and the transistors materials and configuration, measured mobilities varied in the range between 0.02 and 0.8 cm 2 V −1 s −1 …”

“…As already mentioned in Section , TIPS‐pentacene is frequently employed in the fabrication of inkjet‐printed OFETs . The best performances, in terms of carrier mobilities (≈1 cm 2 V −1 s −1 ), were achieved by James et al who printed a TIPS‐pentacene and polystyrene blend dissolved in tetraline and deposited on the top of Au drain and source electrodes fabricated on a bottom‐gate silicon wafer.…”

Inkjet-printing is one of the most important fabrication techniques in the field of printed electronics. Its main advantages include the possibility of fabricating, at ambient conditions and by employing a digital layout, a large variety of electronic devices on different types of substrates, including flexible plastic ones. In this paper, the utilization of inkjet-printing as an important fabrication tool for the realization of organic transistors and circuits/sensing systems based on such type of transistors is reviewed. The most important aspects of the fabrication process, including ink formulation, printing deposition, and postprinting treatment, are described in detail. The most significant examples of inkjet-printed organic transistors of different types (field-effect, electrolytegated, and electrochemical) are presented and finally an overview of their applications as building blocks of more complex electronic circuits and systems for the detection and quantification of specific measurands is provided.

Recently, the research in solution-based, small-molecule organic semiconductors has achieved great progress, although their application in organic electronics devices is still restricted by a variety of issues, including crystal misorientation, morphological nonuniformity and low charge-carrier mobility. In order to overcome these issues, hybrid material systems that incorporate both organic semiconductors and additives have been successfully demonstrated to control crystal growth and charge transport of the organic semiconductors. In this work, we first review the recent advances in the charge-carrier mobility of the organic semiconductors, followed by a comparison of the different additives that have been reportedly blended with the semiconductors, including polymeric additives, small-molecule additives and nanoparticle based additives. Then we will review the important nanoparticles employed as additives to blend with solution-based, organic semiconductors, which effectively improved the semiconductor crystallization, enhanced film uniformity and increased charge transport. By discussing specific examples of various well-known organic semiconductors such as 6, 13-bis (triisopropylsilylethynyl) pentacene (TIPS pentacene), we demonstrate the essential relationship among the crystal growth, semiconductor morphology, dielectric properties, and chargecarrier mobilities. This work sheds light on the implementation of nanoparticle additives in highperformance organic electronics device application. the application of the organic semiconductor in thin-film transistor and other electronics device fabrication. Throughout the discussion of these specific examples that mainly involve small-molecule organic semiconductors, we showcase that this work can be used to control the crystallization and electrical performance of other newly-discovered, high-performance, semiconducting materials. Advances in organic electronicsIn this section, we will review the various advances in charge-carrier mobilities and device application that have been recently achieved in the field of organic electronics. The following discussion will be mainly focused on various solution-processed, small-molecule, organic semiconductors.The mobilities in solution-processed, small-molecule, organic semiconductors have been reported to be compared to or even far surpass the mobility of amorphous silicon. For example, Asare-Yeboah et al developed a temperature-based method which exposed the substrate to a gradient temperature and induced a solubility difference of a p-type small-molecule semiconductor 6, 13-bis (triisopropylsilylethynyl) pentacene (TIPS pentacene) [18]. TIPS pentacene crystals grew from the lower temperature side of the substrate towards the higher temperature side, forming well-aligned ribbons across the whole substrate. A mobility of up to 0.5 cm 2 V −1 s −1 has been reported from the TIPS pentacene OTFTs based on an ITO/PET flexible substrate by using the temperature-based alignment technique. Wade et al demonstrated a zone casting metho...
