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 1 donor state and an acceptor. Pairs of donors with B, which acted as donors, were also detected. The diffusivities at 273 to 1343K were described by:

D (cm2/s) = 1.1 x 10-3 exp[-0.66(eV)/kT]
