Nano Au-decorated boron nitride nanotubes: Conductance modification and field-emission enhancement

Chen, Hua; Zhang, Hong-Zhou; Fu, Lan; Chen, Ying; Williams, James; Yu, Chao; Yu, Da Peng

Description

This letter reports the electrical and field-emission properties of Au-decorated boron nitride nanotubes (Au-BNNTs). The insulating BNNTs become metallic after Au coating as the Au coverage exceeds a critical value. The Au decoration modifies the work function of the BNNTs and, as a consequence, the field-emission current densities of Au-BNNTs are significantly enhanced. Correspondingly, the turn-on field of the Au-BNNTs is reduced to one third and the emission current density is increased by...[Show more]
