Tantalum nanotube arrays via porous-alumina-assisted electrodeposition from ionic liquid: Electrical characterization
Original language description
Tantalum nanotube arrays were prepared via porous anodic alumina (PAA) assisted electrodeposited (ED) on substrates. The ED was performed following the electrochemical/chemical preparation of PAA template on a layer of refractory metals sputtered onto aSi-wafer, without any additional steps needed usually for making the ?bottom? side of the PAA template conductive. Mechanically stable, free-standing and spatially-separated tantalum nanotubes were electrodeposited potentiostatically at -1.4V vs. Pt witha high uniformity and population density across the sample surface. The films were characterized by scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) in solution and after making top metal electrodes via a magnetron sputtering method. The electrical charge resistance of the ED Ta nanostructures was estimated to be about 50 ? cm2. Potential applications of films developed here are as nanostructured electrodes for capacitors, chemical sensors, switching a
