Template-less Synthesis of Coded Au Nanowires

Morphological coding of nanostructures represents a capability in rapid modulation of structural features and most importantly, the transcription of information into nanoscale. Exploiting the regioselectivity in the template-less electrochemical synthesis of ultrathin Au nanowires, we show that rapid alternation of applied potential would cause corresponding change in the width of the emerging nanowire segments. By understanding the growth kinetics, a strong correlation between the nanowire morphologies and the deposition potential is established and applied in emulating the Morse code.

Automated summary

By understanding the growth kinetics, we are able to achieve rapid modulation of structural features and transcription of information into nanoscale in nanostructures, and utilize regioselectivity to emulate Morse code.
