Local optical characteristics of semiconductor surfaces
Original language description
Photoluminescence (PL), photoreflectance (PR) and photocurrent (PC) spectroscopic techniques have demonstrated to be helpful experimental methods to investigate the properties of bulk semiconductors, microstructures, surfaces and interfaces. We present near-field local PL, PR and PC spectroscopic study of semiconductor quantum structures using a technique of reflection Scanning Near-field Optical Microscope (SNOM) in combination with Nitrogen laser and tuning dye laser and with He-Ne laser. RefleectionScanning Near-field Optical Microscope (SNOM) employs an uncoated and/or Au-metallized single-mode fiber tip both as nanosource and a nanoprobe. In the illumination-collection hybrid mode, the first one serves to excite the semiconductor sample and the second one to investigate characteristics of the structure and to pick up the PL and PR intensity reflected from the sample. In the illumination mode, the nanosource illuminates locally the semiconductor structure, and excites the photoele
