Fabrication of Ag-TCNQ nanowires — •Markus Baranowski and Michael Huth — Physikalisches Institut, Johann Wolfgang Goethe-University, Frankfurt am Main, Germany
A method is presented which allows to grow silver-tetracyanoquinodimethan (Ag-TCNQ) nanowires by utilizing porous aluminum oxide (Al2O3) templates. Ag-TCNQ nanowires are interesting because of their unique electric properties. They exhibit a reproducible I-V hysteresis which shows electrical switching [1]. Promising application of the Ag-TCNQ nanowires are therefore memory devices. The Ag-TCNQ nanowires are fabricated by sputtering Ag on one side of porous Al2O3 templates and subsequent covering of the Ag surface with an adhesive. Afterwards a solution reaction of TCNQ solute in acetonitrile is used to obtain the Ag-TCNQ nanowires. With this technique simultaneous fabrication of nanowires with 200nm diameter and a length of up to 15µm can be achieved.
