The development of a simple and reliable fabrication method for well-ordered semiconducting carbon nanotubes (CNTs) at room temperature is very important for future applications. We have succeeded in fabricating well-ordered CNT devices, which are linearly joined with two different diameter tubes and show a semiconducting characteristic at room temperature, by using well-ordered porous anodic alumina...
We have studied, for the first time, the field emission from the film, prepared by a spray method, of the finely dispersed black core material, including multi-walled carbon nanotubes (MWNTs), fabricated by arc discharge. We dispersed the black core material by using an ultrasonic processor and found that the dispersed ones were much finer than those observed when treated with a ball mill and normal...
We have developed a new gas-phase synthesis technique to produce carbon nanotubes (CNTs) with a continuous process and at high temperature, by using a thermal plasma jet. A thermal plasma jet was generated by applying a direct current of 100-300 A, using Ar as the plasma gas with a flow rate of ~6 ksccm. The temperature of the thermal plasma jet was very high (~10 4 K) and the velocity was...
