Synthesis, Microstructural and Dielectric Characterization of Nanodielectrics

Nanostructured dielectric materialsDielectric materials are a special class of high-quality electronicElectronics-grade materials having confinement of at least one of its dimensions at the nanoscale for advanced nanoelectronics, nanodevice, optical, and many other potential applicationsApplications. Nanodielectric materialsNanodielectric materials became significantly important with the progression of the miniaturization of device dimensions. Currently, transistor fabrication technology has seen many advancements reaching almost atomic scales that inculcate very high quality and ultrathin gate dielectricDielectrics layers. High capacitance nanodielectricNanodielectrics gate materials are extremely important in high-throughput thin-film transistors (TFTs) for potentially hysteresis-free and low-voltage action. Moreover, organic–inorganic hybrid nanodielectric materialsNanodielectric materials are the most-sought-after for flexible electronicsElectronics on account of mechanical bendability. Organic nanodielectric materialsNanodielectric materials are highly desired for advanced low-voltage operating carbon nanotube (CNT)-based TFTs and for complementary logic gates applicationsApplications. Another fact is the ease of deposition of dielectricDielectrics solution over plastic substrates for flexible nanoelectronic applicationsApplications. Other categories of nanodielectric materialsNanodielectric materials include carbon black composited with polymersPolymer to form nanocompositesNanocomposites, silica aerogel, epoxy microcomposites enhanced with nanosized clays, crystalline dielectric materialsDielectric materials, and nanometric dendrimers. Next-generation applicationsApplications can be classified into increased stress, higher temperature, stress-grading, and surface modification submissions. Engineered nanodielectricNanodielectrics layers are of paramount importance for self-cleaning or easy-to-clean surfaces for outdoor applicationsApplications in cars and windows, for example. The main feature of a high static contact angle provides for a nonwetting surface. Next-generation highly efficient insulation materials are the need of the hour that is free from unambiguous dielectricDielectrics breakdown character including surface flashover between the dielectricDielectrics surface and vacuum or surrounding environment. Nanoscale fillersFiller, nanodielectric materialsNanodielectric materials, and nanoparticles have been synthesized and worked on for state-of-the-art applicationsApplications.
