Preparation and Field Emission Capability of Silver Tetracyanoquinodimethane Nanowire Array

Abstract

Abstract:

The well-aligned silver 7,7,8,8-tetracyanoquinodimethane(AgTCNQ) nanowire array was prepared with the anodic aluminum oxide(AAO) template method. The size, length and morphology of AgTCNQ nanowires were well characterized via scanning electronic microscopy(SEM) and transmission electronic microscopy(TEM). It is revealed that the AgTCNQ nanowires are uniform and both the length and diameter are controllable. The field emission property of the AgTCNQ was studied and the result revealed that the template-synthesized AgTCNQ nanowire array had excellent field emission property. The turn-on electric field of electron emission is 1.51 V/μm, and the F-N enchancement factor is 21.4, which suggest that AgTCNQ nanowires are perfect candidates for field-emitting materials.

Key words: Silver 7,7,8,8-tetracyanoquinodimethane(AgTCNQ), Field emission, Nanowires
