Development of carbon nanotubes for field emission application

Four Carbon Nanotubes (CNTs) samples were grown by Thermal Chemical Vapor Deposition (TCVD) using 4 different growth times of 2, 4, 6, and 8 min. 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...
