We optimized the triode structure for carbon nanotube electron beam(C-beam) application with carbon nanotube emitters grown with resist-assisted pattering process. The CNT emitters grown through the RAP process have a structure in which a number of CNTs are congregated, and the graphitization post-treatment process proceeded in order to enhance their adhesive strength and stability. The gate mesh...
We have examined the tunneling potential between two carbon nanotubes (CNTs) immersed in a dielectric matrix, with each pair of them being in a different geometrical configuration to each other. We have found that this potential may differ significantly from pair to pair even when the distance between them is the same and hence the transmission coefficient between CNTs is heavily dependent on geometrical...
Stable field emitters were developed using carbon nanotubes (CNTs) composite pastes with nickel (Ni) buffer layer. The paste CNT emitters showed lower threshold for field emission but which have short lifetime and unstable emission current in high emission current. In this paper, we developed the simple process of inserting Ni buffer layer between the CNT emitters and substrate. The paste CNT emitters...
