摘要
A process for transferring carbon nanotube ( CNT) arrays from a silicon wafer to an alumina substrate coated with Ag paste is proposed. A current density of up to 325 mA cm(-2) at an electric field of 2.4 V mu m(-1) was achieved. The influence of the patterned size and the length of carbon nanotubes on the field emission properties were investigated. Through this transfer method, the adhesion between the CNTs and the substrate is enhanced and the current density and turn-on voltage are improved. The effects of the microstructure of the emitting sites at the CNT tip on the current density were also studied.
