Abstract(in English) | A novel photoluminescence (PL) microscope using a conventional optical system has been developed to obtain monochromated PL mapping at a low temperature down to 15 K with a spatial resolution in sub-μm range. The objective and the cooled sample were put in the identical vacuum chamber in order to take thermal insulation between them. The spatial resolution of the microscope at a low temperature was confirmed to be almost equal to the theoretical limit expected from numerical aperture, i. e., 0.3 μm at a wavelength of 488 nm. A monochromated PL image at a wavelength of 666 nm for GaAs_<0.67>P_<0.33> epilayer on GaP was demonstrated with a spatial resolution of 0.5 μm at 20 K. The influence of a surface defect on an excitonic PL emission of 4H-SiC was discussed based on a PL image. |
