Development of Carbon Nanotubes for Optical Applications

I am pleased to have an invited talk in ICCE-nano2015.icce-nano-background_4

(Invited) “Development of Carbon Nanotubes for Optical Applications”, H. Furuta, ICCE-nano2015, (Chengdu, China, 15 Jul. 2015).

In the presentation, I reviewed physical, electrical and optical properties of carbon nanotubes and their applications. I also showed recent works in my laboratory including “Anisotropic Optical Properties of Carbon Nanotube Forests.”

Optical and THz properties of carbon nanotube forests

We showed a poster presentation in NT15, entitled “Optical and THz properties of carbon nanotube forests”. Anisotropic optical index of vertically aligned CNT forests are interpreted by the anisotropic electorical conductance of nano-rods of CNTs.

Electrical conductance behavior of thin Ni catalyst films during intermittent direct current magnetron sputtering

We are pleased to announce that our paper entitled “Electrical conductance behavior of thin Ni catalyst films during intermittent direct current magnetron sputtering” will be published in J. Vac. Sci. Technol. A.

J. Vac. Sci. Technol. A, 32(3) (2014) 031502-1.

  In this article, in-situ electrical conductance measurement of Ni catalysts on insulating substrates during magnetron sputtering deposition were developed for the density and size control of the Ni catalyst for CNT growth. Increase of electrical conductance of thin film in the initial stage of magnetron sputtering deposition of Ni on insulating SiO2 substrates was investigated for preparation of carbon nanotube (CNT) catalyst. 

  It was demonstrated that the electrical conductance measurement during sputtering deposition was a convenient tool to examine the structures in the deposited film.
