- 論文の詳細を見る
We observed the field electron emission of the technologically useful current density of 10 mA/cm2 at an extremely low threshold electric field ($E_{\text{th}}$) of 1.0 V/μm, from an array of pillars of aligned carbon nanotube bundles, which were grown on a Si substrate by thermal chemical vapor deposition. Adjusting the distance between the neighboring pillars ($R$) and the pillar height ($H$) to the optimal condition ($R/H = 2$) can effectually enhance the field concentration, resulting in a highly efficient electron emission. The obtained $E_{\text{th}}$ is 1/2–1/3 times lower than the best values that have been reported to date.
