Carbon Nanotubes: Re-Inventing Organics
Abstract:
Cathleen Thiele, Technical Analyst, IDTechEx: Carbon nanotubes and graphene exhibit extraordinary electrical properties for organic materials, and have a huge potential in electrical and electronic applications such as sensors, microelectronic and semi-conductor devices, field emission displays (FEDs), nanoelectrodes and energy conversion devices (e.g., fuel cells and batteries).
Depending on their chemical structure carbon nanotubes (CNTs) can be used as an alternative to organic and inorganic semiconductors, as well as conductors, but the cost is currently the greatest restraint. However, that has the ability to rapidly fall as applications grow and manufacturing costs improve. Interest is high as CNTs have demonstrated carrier mobilities which are magnitudes higher than silicon, meaning that fast switching transistors can be fabricated. This is in contrast to polymer organic materials that many companies are developing for transistors, where the mobility is currently very low, severely restricting possible uses. Seventy-eight organizations working on the topic are profiled in a new IDTechEx report.
