Witrynaan impurity in Portland cement, and it can be generated and given off during casting, welding, and cutting operations (for example, of stainless steel), even if it was not originally present in its hexavalent state (NTP, 2005; OHCOW, 2005; OSHA, 2006). 1.4 Environmental occurrence Chromium (VI) can occur naturally in the 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-
