A diffusion mechanism whereby atomic motion is from interstitial site to interstitial site 晶体扩散机制的一种。间隙原子由一个间隙位置迁移至邻近的间隙位置所构成的扩散。
2.
But above 700 , the resistivity decreases suddenly , as the nb ion diffuse from linbo3 into zno and occupied the interstitial sites . nb ions , as donor doping in zno film , Linbo3中的nb扩散到zno中去,占据间隙位置,相当于失主能级,形成电阻率低的n型zno薄膜。
