查询词典 nitride

The thesis are divided into two parts. In the first part, we used 2,4,6-trichloro-1,3,5-triazine as the precursor to react with sodium which have been achieved by decomposing sodium hydrate at 623 K. At a low reaction temperature of 623 K, carbon nitride nanosphere、porous carbon nitride material and byproduct sodium chloride, would be produced.

选择同质或者异质的基质材料；在基质材料上外延生长形成变换叠加的垒层和阱层，在垒层与阱层的界面和阱层与垒层的界面掺入施主杂质和受主杂质，得选择超晶格位置掺杂的p型III族氮化物材料，其中，每个生长周期的步骤为：生长带隙较宽的垒层，同时掺入受主杂质；生长施主杂质或受主杂质δ掺杂层；生长非掺的带隙较窄的阱层；生长受主杂质或施主杂质δ掺杂层；在N 2 气氛下对所得的选择超晶格位置掺杂的p型III族氮化物材料退火，即得目标产物。
