The commercial huddles of carbon nanotube devices

It has been passed over a decade since the first 5-inch diagonal carbon nanotube (CNT) field emission display was demonstrated. The most of technical issues were solved and the device showed promising performances at that time. However, it is not shown on a market as a new display device although alternative devices like OLED and PDP are on sale. Now scientists and engineers are developing new CNT based devices as like rf amplifiers, THz sources, array e-beam lithography tools, and X-ray sources. The hidden obstacles for the commercialization of CNT devices like the lack of standardization of detailed properties and inspection limitations of process steps should be carefully considered to avoid another failure. The presentation will cover unaddressed but critical huddles for CNT devices commercialization.
