Witryna17 kwi 1995 · Impurity effects of In 3+ and Cr 3+ on the electronic states of the high temperature phase of Fe 3 O 4 have been investigated by means of Mössbauer spectroscopy. The effects of the impurities were negligible for the A-site spectrum, whereas they were obvious for the B-site spectrum. Witrynamechanism of the impurity bands assisted carrier relaxation, where the impurity bands within the bulk band gap introduced by Cr doping provide significant recombination channels for the excited electrons. This work directly illustrates the dynamic process of the carriers in Cr doped Bi2Se3, which is expected to promote the applications of (Bi1-
