Metallic Nanowires and Porous Alumina Membrane Synthesis System

Instrument types

We have developed a system to fabricate porous alumina membranes with pore size of 10-100 nm and metallic nanowires with lengths of 10-50 ┬Ám. The system contains a dc voltage supply (0-60 V, 0-2A), a multimeter, anodizing bath and depositing cell, cooling bath, heating plate and stirring plate. High quality single-crystal metallic nanowires (Au, Ag, Cu, Sn, Pb, Bi and Zn) are fabricated by controlling the deposition parameters (temperature, applied electric potential, etc.). Polycrystalline (Rh, Pt, Co, Ni) or striped nanowires (Co/Cu) are also achieved.
