Abstract
A nanomaterial ribbon patterning method includes: forming a first nanomaterial layer having a first threshold strain on an upper surface of a substrate; forming a second nanomaterial layer on an upper surface of the first nanomaterial layer; forming a thin layer having a second threshold strain smaller than the first threshold strain on an upper surface of the second nanomaterial layer; generating plural cracks on the thin layer and the second nanomaterial layer by applying tensile force to the substrate; placing a mask on an upper surface of the thin layer; removing the mask and peeling off the sacrificial layer on the upper surface of the thin layer; and removing the sacrificial layer to form a nanomaterial ribbon pattern.
