Diamond as a basic semiconductor material, just like others, is needed for n-type conduction as well as its p-type counterpart. 与其它半导体材料一样,金刚石作为基本的半导体材料,首先需要实现的就是p-n结,具体说就是能够合成p-型和n-型导电材料。
Anatase TiO2 with oxygen vacancy is n-type conduction and with titanium vacancy is p-type conduction. 具有氧空位缺陷的锐钛矿相TiO2为n型导电,存在钛空位缺陷时为p型导电。
