Abstract Submitted to the NANOTUBE'05 Conference:

Field emission display (FED) having carbon nanotube (CNT) emitters has been fabricated for several years in Samsung [1]. The phase shift from metal electron emitter to CNT has given us great success not only in the business field, but also in the academic field. In this presentation, the parameters to enhance field emission property of CNT will be discussed. We will also describe secondary electron emission and photoemission property of CNT incorporated with MgO and CsI.

The study and precise control of CNTs in the form of paste and CVD grown thin films gave us much information to use CNTs as a better electron emitter. Four components in CNT paste are CNT, frit, filler, and vehicle [2]. The pretreatment of CNT, using proper frit and vehicle, and modifying frit resulted in 10 times larger emission current and half value of operating bias. The CNTs are also directly grown on the FED structure by CVD method. The emission properties of CVD grown multiwalled CNT are similar with those of physically synthesized single wall CNTs.
