Abstract
The diffusion of iron impurities in zinc selenide (ZnSe) during hot isostatic pressing (HIP) in the temperature range T = 1000–1300 °C and pressures P = 100–190 MPa has been investigated. The iron concentration and its distribution over the sample volume with a step from 20 to 50 μm was determined by IR spectroscopy in combination with an IR microscope. The diffusion coefficients of Fe in ZnSe at various temperatures and pressures were determined. The diffusion coefficients of Fe in ZnSe at P = 100 MPa and T = 1000 °C were (5.3 ± 0.6)x10−10 cm2/s, T = 1300 °C were (9.4 ± 0.9)x10−9 cm2/s. It is shown that the temperature dependences are described by the Arrhenius equation, and the isostatic pressure does not affect the value of the diffusion coefficients.
