Original Abstract

Visible light Scanning Near-field Optical Microscopy (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 and allows a spectroscopic measurements. In this work, we measured the SNOM-induced photocurrent in GaAs devices. Our goal was to obtain spatially resolved measurements of the photocurrent response across the various layers in crystalline GaAs solar cells, by studying the cleaved edges of the cells.
