The behavior of the type-3d transition metal impurity was investigated by using deep-level transient spectroscopic and Hall-effect measurements. Deep-level transient spectroscopic data revealed double donors and an acceptor. The diffusivities at 873 to 1423K were described by:

D (cm2/s) = 1.2 x 10-1 exp[-2.05(eV)/kT]
