Hall measurements and combined Hall and DLTS measurements for cobalt-doped n- and p-type silicon are carried out to reveal cobalt levels and cobalt-related levels in silicon. The impurity level assignment of cobalt in silicon, donor or acceptor, is well established. It is found that cobalt has an amphoteric nature in silicon, i. e. cobalt center has neutral, negatively and positively charged states.
