Thinned barrier layer AAO

Product Name: Thinned barrier layer AAO

model:

Time: 2018 - 12 - 27

Using AAO as template, various one-dimensional nanomaterial arrays can be easily fabricated by electrochemical deposition. Generally, double-pass AAO templates are used. One layer of metal conductive layer is evaporated on the side of the template, and then nanomaterials are prepared by DC electrochemical deposition. However, double-pass AAO templates are fragile and inconvenient to operate. Evaporation of metal conductive layer also increases the cost and complexity of the experiment. If single...
