Abstract :
We investigated the contact resistivities of Au//M(=Pd or Pt)/Zn/Pd/p-InP, focusing on the role of the third metal, M. Both the lowest specific contact resistivity of 7×10-6 Ω·cm2 and a flat diffusion front were obtained for a sample with a Au/Pt/Zn/Pd/p-InP contact material after annealing at 400°C for 4 min.
