Molecular electronics and spintronics using nano-carbon molecules

Single-walled carbon nanotubes (SWNTs) and C60-fullerenes are believed to be one of the most potential molecules to realize novel molecular electronics and spintronics devices because of their unique low-dimensional structures and electronics properties.
In this talk, I pick up two topics, that is, realization of solution-processed random-network SWNT-FETs for flexible devices and spin-dependent transport via SWNTs and C60s.
In the first topic, I introduce the device characteristics of the solution-processed SWNT-FETs, which exhibit better performance than the other organic FETs, from view points of carrier doping and Schottky barrier modulation.
In the second topic, I focus on the spin-dependent transport via molecules, which is still controversial. Based on some careful investigations, I have firstly succeeded in observing spin-dependent transport via C60s at room temperature. This success was induced by fabricating novel C60-Co nano-composites and also by bypassing two serious problems, (i) large contact resistance at a interface between molecules and ferromagnets (ii) Ill-defined interface formation at the interface. The detail will be presented in the talk.
