However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.

把两种或两种以上材料组合起来实现优异性能材料的方法是一种经常使用并行之有效的方法，本论文就是对GaP、GaAs与GaN形成合金系GaP_(1-x)N_x和GaAs_(1-x)N_x进行基础性研究的结果，人们预测这种合金系的禁带宽度应在磷化镓的2.261eV(或砷化镓的1.43eV)到氮化镓的3.39eV之间，如果能制成上述合金系则是很有意义的，它是很有希望的蓝色发光材料。

The results showed that the addition of the rare earth alloy powder can refine and disperse oxide particles. Through energy spectrum analysis, it was found that the rare earth congregates to Ti and the interface between metal matrix and diamonds.
