Nanoparticles with tunable shape and composition fabricated by nanoimprint lithography

Cone-like and empty cup-shaped nanoparticles of noble metals provide extraordinary optical properties for optical nanoantennas or nanoresonators. However, their large-scale production is difficult. We present a fabrication approach to achieve arrays of nanoparticles with tunable shape and composition by a combination of nanoimprint lithography, hard-mask definition and metal deposition.
