磷化

This article mainly reviewed the discovery and the research course of natural phosphine ,namely,how phosphine coming into being,and whether phosphine being universal existed gas in natural environment such as in aerosphere,biosphere,hydrosphere.

磷化氢是剧毒的、十分活泼的无色气体，具有强的还原性，在光照、空气等作用下，极易转化为磷的其它形态。

本研究将使用在矽制程上已相当成熟的金属镶嵌技术运用於砷化镓及磷化铟基材之铜金属化制程中，验证其可行性。

Study on the preparation of γ-alumina-supported molybdenum phosphide hydrofining catalysts;2. Silica-supported molybdenum phosphide s were prepared in a fixed bed reactor by an in situ reduction method from their oxidic precursors.

以SiO2为载体，用钼酸铵和磷酸氢二铵作钼源和磷源，采用共浸渍法制备了负载型磷化钼氧化态前体；在固定床反应器上，用H2原位还原制备了MoP/SiO2催化剂。

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。
