Randomly aligned CNTs were obtained. The height of the obtained CNT films varies from 0.71µm at 2 min to 2.51µm at 8 min. Raman spectrum of the CNT grown for 8 min shows higher I_D/I_G ratio of 1.298 compared to 1.106 for 2 min growth time. Field emission characteristics of the CNT with 2 min growth time achieved higher turn-on E-field and maximum current density of 1 V/µm and 20.7mA/cm2 respectively. The result suggested that the field emission characteristics of CNT depend simultaneously on both CNT height and structural properties. | URI: | http://hdl.handle.net/10356/67371 | Schools: | School of Electrical and Electronic Engineering | Rights: | Nanyang Technological University | Fulltext Permission: | restricted | Fulltext Availability: | With Fulltext |
