“…In general, when a high electric eld is applied, forming a negative electrical potential on a conductor surface, the electrons inside the conductor may penetrate the conductorvacuum potential barrier, emitting out into the vacuum by the quantum tunneling effect.

“…where f is the height (maximum of E barrier (x)) of the potential barrier. 24,25 It can be seen in formula (2) that J would be larger when f is lower and E local is higher. It has been reported that to achieve a considerable eld emission current density, the electric eld on the conductor surface should be in the order of 10 7 V cm À1 .…”

Electric field-dependent conductivity achieved for carbon nanotube-introduced ZnO matrix

In contrast to the carbon nanotube (CNT)-introduced insulating matrix, the electric conductivity of CNTintroduced ZnO matrix is not only dependent on the CNT content, but is also dependent on the applied electric field when the CNT content approaches the electrical percolation threshold. From the viewpoint of circuit interconnections in a microscope, there are two conductor-semiconductor contact structures equivalent to Schottky junctions being series connected between the adjacent CNTs, forming electrical fielddependent impedances between adjacent CNTs in the CNT-introduced ZnO matrix. Based on the electrical percolation theory, the CNT-introduced ZnO matrix may be seen to be a comprehensive circuit composed of a large amount of electrical field-dependent impedances connected in series and in parallel. On increasing the applied electric field, these impedances would be decreased, leading to an inevitable decrease in the resistivity of the CNT-introduced ZnO matrix. In essence, the electric field-dependent conductivity for a CNTintroduced ZnO matrix is a macroscopic quantum tunneling effect. From a practical perspective in electronic technologies, such a distinctive performance in electrical conductivity would have promising applications.
