We have measured the diffusion of aNi radiotracer into polycrystalline NiO. nominally doped with 0.1% Cr (Cr/Ni ratio) in the temperature range 600 to 900ยฐC. The experiments show that Cr doping increases diffusion of Ni in the oxide lattice, but decreases diffusion of Ni along grain boundaries provi
The experimental results of an investigation of the steady-state motion of individual grain boundaries (GBs) of natural deformation twin and individual twin GBs in bicrystals and tricrystals with triple junction (TJ) are obtained. For experimental observation of GB mobility from the dependence on GB
The effective minority carrier lifetime in polycrystalline semiconductors is determined in terms of the grain size and the recombination velocity at the grain boundaries. The effect of the grain boundaries is to reduce the effective lifetime when the grain size is smaller than few diffusion lengths.
