無機化學-半導體

Question

In addition to the doping described in this chapter, n-type semiconductors can be formed by increasing the amount of metal in ZnO or TiO2, and p-type semiconductors can be formed by increasing the amount of nonmetal in Cu2S, CuI, or ZnO.Explain how this is possible.

麻煩了,謝謝:)

By increasing the intensity etc. of (Cu)Zn, which help to build up the Zn in ZnO, through the maximizing effect of (p-->n) type semi-conductors.

This is one explanation.
