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...

“…The device also can be peeled off. Furthermore, Afsharimani and Nysten [39] prepared PVA thin films by spin-coating and utilized them as polymer gate dielectrics to fabricate transistors. The transistors show ambipolar behavior with hole and electron mobilities in a low voltage range, indicating a promising potential future in dielectrics.…”

“…Regarding dielectric polymers, adding a small amount of nanofillers into them to prepare nanocomposites would further enhance their dielectric performance. The chemical structure, surface morphology, and preparation method, as well as the additives, all have an effect on the dielectric properties of the nanocomposites [39,181,182,183]. Conductive and high dielectric constant nanofillers, such as CNTs, GO, Al 2 O 3 , and SiO 2 , all have the potential to improve dielectric performance.…”

With the continuous increase in the production of electronic devices, large amounts of electronic waste (E-waste) are routinely being discarded into the environment. This causes serious environmental and ecological problems because of the non-degradable polymers, released hazardous chemicals, and toxic heavy metals. The appearance of biodegradable polymers, which can be degraded or dissolved into the surrounding environment with no pollution, is promising for effectively relieving the environmental burden. Additionally, biodegradable polymers are usually biocompatible, which enables electronics to be used in implantable biomedical applications. However, for some specific application requirements, such as flexibility, electric conductivity, dielectric property, gas and water vapor barrier, most biodegradable polymers are inadequate. Recent research has focused on the preparation of nanocomposites by incorporating nanofillers into biopolymers, so as to endow them with functional characteristics, while simultaneously maintaining effective biodegradability and biocompatibility. As such, bionanocomposites have broad application prospects in electronic devices. In this paper, emergent biodegradable and biocompatible polymers used as insulators or (semi)conductors are first reviewed, followed by biodegradable and biocompatible nanocomposites applied in electronics as substrates, (semi)conductors and dielectrics, as well as electronic packaging, which is highlighted with specific examples. To finish, future directions of the biodegradable and biocompatible nanocomposites, as well as the challenges, that must be overcome are discussed.

“…The dissociation of C n H 2n+1 OH adsorption on the Si (111)-7 × 7 surface is a prominent example, where the new bonds (Si-H) and (Si-C n H 2n+1 O) are formed by the reaction between the alcohol gases and Si atoms. After comparing the dissociation process in detail, the influence of CH 3 OH adsorption on different metal atomic structures was explored gradually [16][17][18][19]. Further, with our understanding of some typical metal depositions, they can also be used to explore the characteristics of alcohol adsorption.…”

Metal atoms were deposited on an Si (111)-7 × 7 surface, and they were adsorbed with alcohol gases (CH3OH/C2H5OH/C3H7OH). Initially, CnH2n+1OH adsorption was simply used as an intermediate layer to prevent the chemical reaction between metal and Si atoms. Through scanning tunneling microscopy (STM) and a mass spectrometer, the CnH2n+1OH dissociation process is further derived as the construction of a surface quasi-potential with horizontal and vertical directions. With the help of three typical metal depositions, the surface characteristics of CH3OH adsorption are more clearly presented in this paper. Adjusting the preheating temperature, the difference of thermal stability between CH3O– and H+ could be obviously derived in Au deposition. After a large amount of H+ was separated, the isolation characteristic of CH3O– was discussed in the case of Fe deposition. In the process of building a new metal-CH3O–-H+ model, the dual characteristics of CH3OH were synthetically verified in Sn deposition. CH3O– adsorption is prone to influencing the interaction between the metal deposition and substrate surface in the vertical direction, while H+ adsorption determines the horizontal behavior of metal atoms. These investigations lead one to believe that, to a certain extent, the formation of regular metal atomic structures on the Si (111)-7 × 7-CH3OH surface is promoted, especially according to the dual characteristics and adsorption models we explored.
