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. Pairs of donors with B, which acted as donors, were also detected. The diffusivities at 287 to 363K were described by:

D (cm2/s) = 2.4 x 10-3 exp[-0.72(eV)/kT]
