title: Direct nanoimprinting of metal nanoparticles for nanoscale electronics fabrication.
abstract: One-step direct nanoimprinting of metal nanoparticles was investigated to fabricate nano-/microscale metallic structures such as nanodot and nanowire arrays. This was done at low temperatures and pressures, utilizing the low melting temperature and viscosity of metal nanoparticle solutions. Through precise control of the fluidic properties of the nanoparticle solution and the mold design, high-quality nanoscale features with no or negligible residual layer were nanoimprinted. Nanoscale electronic devices were also demonstrated, including nanowire resistors and nanochannel organic field effect transistors with an air-stable semiconducting polymer.
