Ex-situ Characterization of InGaAsP



Alexana Roshko, Kristine A. Bertness


An interlaboratory comparison was undertaken to assess differences in X-ray and photoluminescence measurements from different laboratories. Six InGaAsP specimens, with nominal photoluminescence peak wavelengths of 1.1, 1.3 and 1.5 υm, were measured. Lateral nonuniformity in the specimens dominated the variation in the X-ray measurements. In contrast, the variation among photoluminescence measurements was larger than the variation within individual specimens and allowed differences between measurements to be assessed. Offsets between different instruments were identified, however correlations with variables such as pump wavelength, wavelength calibration, sample temperature, pump power density, and peak identification, as reported by the different laboratories, were not observed.
