Abstract
Carbon nanotubes are considered as one of the best candidates to be used as an emission layer in various applications. There are some drawbacks, which limit the wide use of CNT as field emitters. Mainly, it is a non-uniformity of the tips and degradation of emission current due to the nanotubes burning. In this work, we show the simple and cheap method of highly effective CNT cathodes fabrication. Single-walled CNT are located horizontally on the Si pillars made by Bosch process and demonstrate low field emission (emission starts at 100 V with an anode-cathode distance of 3 µm) and sufficient current densities as large as 8.5 A/cm2 at 200 V bias (2000 µm2 emitting area). Additionally, the comparison with vertically aligned the CNT cathodes is shown.
