Field Emission Display Through CNTs

◆What is Field Emission Display?

Field Emission Theory: By applied a high electric field to a conductor, the effective energy barrier of the conductor surface will reduce and the barrier wall will become low. So the electrons will easily tunnel through the energy barrier and emit from the surface of conductor. Field Emission Display is a kind of display technologies, which works base on the field emission theory. See figure 1,2 and 3 for comparison it with CRT .
