Electronics at the Nanoscale: Challenges & Opportunities for Making Metal Nanowires

Silver, gold and copper nanowires are leading contenders for next-generation nanoscale devices, however, a greater understanding of how they work and improved production methods are needed before they can be widely used, explains a recent review in the journal Science and Technology of Advanced Materials.

“Metal nanowires are used for numerous applications, but our understanding of their mechanical properties remains elusive,” says Nurul Akmal Che Lah, Engineer at Universiti Malaysia Pahang. 

Lah and Colleague Sonia Trigueros at the University of Oxford reviewed methods for synthesising and analysing silver, gold and copper nanowires for molecular-based electronics.

Molecular electronics uses single molecules, or nanoscale collections of molecules, to create electronic components too small to be seen with the naked eye. For example, molecular wires are one-dimensional chains of single metal atoms which conduct electric current. Molecular electronic devices can be used for a wide range of applications from storage media to catalysts and clinical treatments.
