摘要

The L_1 and L_3 edges of Cd and the K edges of Fe and Se have been examined for CdSe and Cd_(1-x)Fe_xSe (x = 0.22) wurtzite crystals by the X-ray absorption technique. The experimental results are compared with the calculated conduction band electronic densities of states of the CdSe and Cd_3FeSe_4 wurtzite crystals (J. Konior, J. Goniakowski, S. Kaprzyk, J. Alloys Comp 328 (2001) 139), respectively. A good agreement is found between the experimental and theoretical results. Then, using the virtual crystal model for Cd_(1-x)Fe_xSe, the hypothetical wurtzite structure of FeSe, denoted as FeSe(w), as well as a hybridized contributions show p-like behavior around Se ions, at about 2 eV below and at 8 and 18 eV above the corresponding energy of the CdSe conduction band minimum. A negligible contribution of FeSe(w) around Cd ion has been ascertained.
