Abstract
The mechanism of nanostructure fabrication by tip-enhanced laser irradiation is discussed. Tip-enhanced laser irradiation involves various ways in which the laser beam is integrated with a scanning probe microscope (SPM). When an SPM tip is irradiated with a laser beam, the tip undergoes thermal expansion to cause surface nano-indentations and significantly enhances optical field in proximity to the tip apex which can heat the sample surface to result in phase change and chemical reaction. The development of a general model for the near-field optical intensity induced by a conductive tip under polarized laser irradiation for the laser assisted SPM was also presented.
