Definition of the Subject

Laser near-field nanomanufacturing is manufacturing nanoscaled materials and complex structures at the nanoscale by means of phase change/explosion with the near-field focused laser beam, whose spot size is usually smaller than its wavelength.

Introduction

Nanofabrication and nanomanufacturing involve manufacturing of materials, structures, devices, and systems down to the nanoscale. There are two basic categories of fabrication, top-down and bottom-up or self-assembly processes, containing a growing number of chemical and physical techniques, such as chemical methods, chemical vapor deposition, molecular beam epitaxy, atomic layer epitaxy, lithography, self-assembly, and countless newly developed techniques. Among those methods, laser-assisted nanomanufacturing plays an important role due to its highly coherent feature. To achieve a ...
