Silicon Nanowire Arrays

$295.00

Vertically aligned arrays of high aspect ratio high density Si nanowires on Si wafers are prepared using metal-assisted chemical etching of silicon (MACE).  These arrays could be made over large areas, with adjustable diameter, density, and length of the nanowires.  A thin layer of catalytic metal remaining at the base of the nanowires can be removed by selective etching.  Standard offerings currently include:

•   Pack of 3 of 1 cm x 1 cm pieces of Si wafer, nanowires on one face, $295/pack
•   One nanowire diameter (200 nm),
•   Three nanowire lengths (0.5, 1 and 3 um)

Description

Silicon nanowire arrays have been utilized in a variety of applications, including Li-ion batteries, solar cells, optical coatings, microfluidics, biosensing and photocatalysis. These materials are especially well-suited for applications that require large surface areas and could take advantage of the broader silicon know-how.
