A New Method for Au Nanowires’ Fabrication and Characterization


Jhe et al. fabricated and characterized Au nanoparticle-aggregated nanowires (ANA-NWs) with liquid-solid coexistence (LSC) phase by using nanomeniscus- induced colloidal stacking method with a guidance of nanopipette/quartz tuning forck-atomic force microscope (QTF-AFM) which operates in a non-contact, small lateral oscillation mode in ambient conditions.

The ANA-NW shows LSC phase which is controlled by retraction speed of nanopipette tip movement and changes with the elapse of time. The NW bends and shrinks via electron illumination and shrinks through heating. The solid-like phase NW,with a length of 15 μm and a diameter of 100 nm,has a relative low elastic modulus about 400 MPa which values are similar to protein crystal or ANA-polymer. There is no significant hysteresis while the strain of this NW is up to 25%.

This fabricated LSC phase ANA-NW and 3D nanoscale structures of particle-aggregated system with various materials can be dealt vital phenomena of low dimensional biological media and progress scientific improvements.
