摘要：

The effect of metal ions adsorption process on the native surface of porous silicon as-anodized is reported in this paper. The adsorption effect is discussed in term of the negative potential of native surface of porous silicon due to the hole depletion during anodization, and the negative potential vanishes as the sample is stored above one month. In the beginning of the electrodeposition process, the current density decreases with time under a certain voltage and the exponential relationship is explained in term of a simple model.
