Abstract

We have carried out spectroscopic ellipsometry measurements for liquid- and solid-phase InSb around its melting point for wavelengths of 300 to 1700 nm. The real and imaginary parts of the complex refractive index for liquid and solid InSb appear to be completely different, with the imaginary part for the liquid being higher than that of the solid. This result agrees with the proposed mechanism for the super-resolution readout effect in optical disks using an InSb film. From a dielectric function analysis, we find that InSb characteristics clearly change from semiconducting in the solid to metallic in the liquid.
