Semiconducting inorganic nanowires (NWs), carbon nanotubes, nanofibers, nanofibers, quantum dots, graphene and other 2D materials have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics and photonics components, coatings and devices. ELECTRONICS.CA PUBLICATIONS, the electronics industry market research and knowledge network, announces the availability of a new report entitled “Nanoelectronics […]

Carbon nanotubes (CNTs) were first observed in 1991. CNTs are extended tubes of rolled graphene sheets. There are two types of CNT: single-walled (one tube) or multi-walled (several concentric tubes). Both of these are typically a few nanometers in diameter and several micrometers to centimeters long. CNTs have assumed an important role in the context of nanomaterials, because of their novel chemical and physical properties. They are mechanically very strong (their Young’s modulus is over 1 terapascal, making CNTs as stiff as diamond), flexible (about their axis), and can conduct electricity extremely well (the helicity of the graphene sheet determines whether the CNT is a semiconductor or metallic).
