Abstract(in English) | Simultaneous fabrication of p- and n-type regions on GaAs pattered substrates is expected to give high-quality p-n junctions. However, their microscopic quality remained unclear due to the unsatisfactory spatial resolution of conventional characterization methods. A near-field optical microscope is utilized for the first time for the optical characterization of lateral p-n junctions. Its high spatial resolution in the measurements of optical properties and surface morphology revealed: 1) The width of the transition region between the p-type and then n-type regions, determined from photoluminescence measurement, was 1.8μm for the junction formed at the upper end of the slope, while 5.5μm for the one at the lower end. 2) On the other hand, the width of the junctions determined from the distribution of light emulsion through current injection, was 1.1μm for both junctions. |
