Effect of calcination conditions on the properties of a new tungsten phosphide catalyst for hydroprocessing 焙烧条件对新型磷化钨催化剂加氢活性的影响
Test method for wavelength of peak photoluminescence and the corresponding composition of gallium arsenide phosphide wafers 磷化砷化镓片的最大光致发光波长及其相应成分的试验方法
Preparation of samples of the constant composition region of epitaxial gallium arsenide phosphide for hall effect measurements 测量霍尔效应用恒定成分范围的外延磷化砷化镓试样的制备
Such an advance would enable engineers to incorporate both electronic and optical devices onto cheap silicon chips rather than being compelled to employ costly - to - make lasers based on “ exotic ” semiconductor materials such as gallium arsenide or indium phosphide 如果成功，工程师就能在成本低廉的矽晶片上同时制作电子和光学装置，不需使用砷化镓或磷化铟等稀有半导体材料，制作成本高昂的半导体雷射。
