Photoreflectance characterization of functionally graded materials. Application to diffusion process analysis
Abstract
Samples made of two slabs respectively of Cu and Zn are heat treated to create concentration gradient, and consequently a thermal properties gradient. Photoreflectance microscopy is used to image these samples with a microscopic resolution. The observed thermal contrast is used to evaluate the distribution of thermal diffusivity.
