Research Topic

Development of novel functional nanocarbon materials and device applications

Research Aim

Nano carbon materials like graphene and carbon nanotube attract the researchers, because of their properties which surpass the semiconducting materials in the past. This group will investigate the surface modification and controlling the electric conductivity of nano carbon materials, and realize their novel functions and device applications.

Role and Need in the Group

The electrical conductivity of graphene and carbon nanotube with chemical modification synthesized by group A01 will be evaluated. We also design the stochastic resonating module based on carbon nanotube to provide the support for the promotion of study conducted by A04.

Research Content

By collaborating with other groups, this group investigate the following topics: 1. Synthesizing the highly ordered carbon nanotube by novel approach. 2. Evaluating the electric property of the device based on nano carbon materials with chemical modification. 3. Designing the stochastic resonating module based on the carbon nanotube electric device, investigating into the relationship with channel number and correlation coefficient, and improving its S/N ratio.
