METHOD FOR DISTINGUISHING SEMICONDUCTING NANOWIRES FROM METALLIC NANOWIRES

摘要

A method for distinguishing semiconducting nanowires from metallic nanowires is related and including: applying nanowires on a substrate; making a metal electrode on the substrate and electrically connected to the nanowires; taking a SEM image of the nanowires and the metal electrode, wherein the SEM image comprises light segments, and each light segment corresponds to one nanowire; and comparing length of each light segment with length of corresponding one nanowire, when the first length is same as the second length, the corresponding one nanowires is a metallic nanowire; when the first length is shorter than the second length, the corresponding one nanowire is a semiconducting nanowire.
