Ultrafast diffusion of Ni and Cu atoms in p+-Si channel was observed. Contact failed at negative contact first, possibly by electron-hole recombination at the negative electrode. Ti diffusion assisted by Cu under high current density was observed in the Cu and Ti multilayered samples. Ti atoms at Ti contact cannot migrate into the diffusion channel but can be carried by Cu atoms. In addition, Cu and Ti easily interdiffused under high current density.
