摘要:
The morphology of anodized p-type Si with the native oxide formed between the back surface of Si and the back metal was studied. Anodization of p-type Si having a 4.2 Angstrom native oxide laver resulted in the formation of approximately rectangular parallelepiped macropores with pore size of 1-3 mum followed by needlelike structures with diameter of 1.7 mum and finally the mirror surface. with an increase of the current density.
