Fabrication of silver/silver-tetracyanoquinodimethane heterogeneous nanowires using nanoskiving method.

In this study, silver/silver-tetracyanoquinodimethane nanowires with excellent microstructure quality are prepared by combining the nanoskiving method with the solution reaction method, and their electrical properties are tested. The perpendicular cutting direction and larger cutting thickness are beneficial to the acquisition of complete and less deformed silver nanowires. Silver/silver-tetracyanoquinodimethane heterogeneous nanowires can be precisely prepared at small droplet concentration, small droplet volume, and 60 s reaction time. The continuity, dimensions, and formation mechanism of nanowires are characterized by atomic force microscope and scanning electron microscope. Raman spectroscopy and transmission electron microscope revealed the successful formation and core-shell structure of silver-tetracyanoquinodimethane nanowires. The electrical properties of silver/silver-tetracyanoquinodimethane heterostructure nanowires show a typical Schottky barrier using a two-point electrical measurement method. This work lays a solid foundation for promoting the engineering application of silver nanowires and silver/silver-tetracyanoquinodimethane heterogeneous nanowires. • Ag-TCNQ nanowires are prepared by nanoskiving and the solution reaction method. • The continuity and dimensions of Ag nanowires are characterized by SEM and AFM. • The core-shell structure of Ag-TCNQ nanowires is confirmed by TEM and Raman. • Different modes in the formation of Ag-TCNQ nanowires are observed by SEM. • The semiconductor properties of Ag/Ag-TCNQ heterogeneous nanowires are verified.
