Outline of Research at the Start

The outline of research is to synthesize a coaxial material of single walled carbon nanotubes coated by boron nitride to improve the carrier mobility in plane nanotubes, reduce the interface traps between CNT and the dielectric and reduce the thermal resistrance in field emission transistors.

Outline of Annual Research Achievements

The purpose of this project is to achieve the application of boron nitride coated single-walled carbon nanotubes in FET devices. We have sucessfully fabricated the device using our material. Moreover, We have also obtained high-purity and high-quality boron nitride nanotube film by removing carbon nanotubes in the heterostructure of carbon nanotube and boron nitride nanotube. Boron nitride nanotubes based heteronanotubes served as a promising platform for investigating the optical properties of transition metal dichalcogenide nanotubes, photoluminescence from molybdenum disulfide nanotubes was observed. The heteronanotubes of boron nitride nanotubes with molybdenum disulfide nanotubes have a great potential for the electronic device applications.
