Semiconductor sub-micro-/nanochannel networks by deterministic layer wrinkling

Semiconductor micro-/nanochannel networks are developed by deterministic layer wrinkling and applied into a fluidics study. Both linear (see figure) and circular nanochannel networks, consisting of a main channel and several perpendicularly oriented branch channels, are created, where the periodicity and position of the branch channels can be tuned and controlled by changing the width of the partially released layers and by applying appropriate lithography.
