Development of an optical near-field microscope — •hamed abbasi1,2, igor shavrin1, and klas lindfors1 — 1University of Cologne, Department of Chemistry, Cologne, Germany — 2University of Bonn (Bonn-Cologne Graduate School for Physics and Astrophysics), Bonn, Germany
Scanning near-field microscopy is an outstanding method to investigate the features of materials on the deeply subwavelength scale. We develop and characterize a probe consisting a single gold nanoparticle for scanning near-field optical microscopy. The tip-particle system is locked to the surface within a distance of a few nanometers. After locking the distance, the surface can be scanned by using a 3-D Piezo stage to locally enhance light-matter interactions.
