Electrical transport investigation of platinum salt nanowires — •J. M. Becker1, L. Ren2, M. Wark2, and R. Haug1 — 1Institute of Solid State Physics, Nanostructure Group, Hannover — 2Institute of Physical Chemistry, Hanover
The investigation of electrical transport properties and the growth mechanism of platinum salt [Pt(NH3)4][HCO3]2 nanowires will be presented. These nanowires have a thickness of 50−100 nm and a length of 500 nm−2.5 µ m. Electrical contacts (Cr/Au) are fabricated by using e-beam lithography and vacuum evaporation. The current-voltage characteristic shows a ohmic behavior at room temperature. This can be related to a metallic structure of these platinum salt nanowires, which means that delocalized states exist at room temperature in growth direction of the wires. The unit cell (space group P 4/m b m) of the platinum salt was determined by using X-ray diffraction.
