Investigation on fabrication of silicon nanopores using an electrochemical passivation etch-stop strategy

Abstract The three-step wet etching (TSWE) method has been proven to be a promising technique for fabricating silicon nanopores. Despite its potential, one of the bottlenecks of this method is the precise control of the silicon etching and etch-stop, which results in obtaining a well-defined nanopor...
