The wet oxidation of AlGaAs with high Al content in a distributed Bragg reflectors (DBR) is studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Some voids distribute along the oxide/GaAs interfaces due to the stress induced by the wet oxidation of the AlGaAs layers. These voids decrease the shrinkage of the Al2O3 layers to 8% instead of the theoretical 20% when compared to the unoxidized AlGaAs layers. With the extension of oxidation time, the reactants are more completely transported to the front interface and the products are more completely transported out along the porous interfaces. As a result,the oxide quality is better.

采用免疫亲和分离与质谱分析相结合的方法,对β2-微球蛋白抗原表位进行了系统研究.完整的抗原分子和已固定在载体(CNBr-activated Sepharose beads)上的单克隆抗体发生免疫亲和反应后,用Endoproteinase Glu-C,Trypsin,Aminopeptidase M和carboxypeptidase Y四种不同的蛋白酶依次酶解抗原分子,并采用基质辅助激光解析电离飞行时间质谱(MALDI-TOF-MS)技术对与抗体连接受保护而未发生水解的肽段进行了研究.结果表明:β2-微球蛋白抗原表位位于整个蛋白分子氨基酸序列的61~67位,即为SFYLLYY.通过合成肽段的分析,证明了SFYLLYY即为抗原表位,与亲和质谱方法分析结果一致.
