Original Abstract

Visible and near infrared Scanning Near Field Optical Microscopy (SNOM) was used to characterize nanostructured semiconductor materials and structures. SNOM is a relatively new technique that combines the versatility of optical microscopy with the resolution of a scanning probe microscope. Light coupled into a tapered optical fiber is used for excitation. The fiber probe is scanned over the sample while being held ~10 nm above the surface. At this point, any number of high resolution (~100 nm) optical measurements can be made. In this work, the SNOM-induced photocurrent in GaAs devices was measured.
