Recent progress in laser assisted digital selective nanomaterial processing

Abstract

Laser is a very unique and useful tool for materials processing with the various parameter choice range. The main mechanism of typical laser processes is photo-induced thermal reaction that generates confined temperature field at a desired position with high controllability. The laser-induced selective temperature rise enables selective chemical reaction for synthesis of nanomaterials in various environment including both gas and liquid environment as well as photophysical processing of nanomaterials through melting or vaporization, represented by laser sintering and ablation processes. In this review, recent progresses in the selective digital laser processing for nanomaterial process and synthesis on various heat sensitive substrate. This laser based process can achieve novel device fabrication which have never been possible with conventional photolithography based electronics fabrication process.
