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- WitrynaACESULFAME WITH IMPURITY B LC50 fishes 1 > 1000 mg/l LC50-96 Hour - fish 12.2.
