We observed the bright bluish-white luminescence with naked eye from carbon nanotube electron beam exposed silicon dioxide (SiO2) thin film on Si substrate. The luminescence shows a peak intensity at 2.7eV (460nm) with wide spread up to 600nm after the C-beam exposed on SiO2 thin film. The C-beam exposure system is composed of carbon nanotube emitters as electron beam source. The brightness strongly...
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 introduced a carbon nanotube electron beam (C-beam) exposure technique for thin films for display devices. As an electron source, the CNT emitters were placed on cathode electrode. Electrons through gate mesh, with higher accelerated energy, impact thin film on the anode plate. For display device application, amorphous silicon (a-Si:H) thin films were deposited on glass substrate and then C-beams...
In this study, we optimized vertically aligned carbon nanotube electron beam (C-beam) with triode structure for cathodoluminescence of Zinc Oxide (ZnO) thin films, which solution process fabricated. Efficient cathodoluminescences were observed with C-beam exposed ZnO thin films. The origin of the luminescence were confirmed by SEM measurement. The luminescence appeared to the structural modification...
