Nanoscale Electronics: Digital Fabrication by Direct Femtosecond Laser Processing of Metal Nanoparticles

Abstract

A digital, direct nanoscale metal patterning method is developed using femtosecond laser digital processing of metal nanoparticles for nanoscale electronics fabrication without using conventional vacuum deposition or a photolithography mask. This method is expected to be a potential alternative to the conventional electron beam lithography method for arbitrary nanoscale direct patterning in single-step, low-temperature, and non-vacuum environments.
