Abstract:	We demonstrate a 10-fold enhancement of the etch rate of sacrificial metals for nanochannel fabrication by galvanic coupling. This results in an etch time for the here examined nanochannels of 10 hours instead of 9 days without galvanic coupling. An additional feature of our device is that we integrated bare electrodes inside the channel. Furthermore, we offer a theoretical explanation of the observed etch rate based on mass transport.
