Thick-And-Thin Nanowire Segments
A simple electrochemical method can be used to prepare semiconductor nanowires that feature segments of alternating density and size along the wire’s length, according to a paper published in ACS Nano (DOI: 10.1021/nn901661z). Multisegmented nanowires could be used as nanometer-scale bar codes in biodetection applications or as basic components of optoelectronic devices that exploit the wires’ periodic properties. Prior studies have led to multistep procedures for . . .
