expitaxy meaning in English

外延

Besides , the growth of gasb expitaxy film was monitored by reflection high energy electron diffraction ( rheed ) . the rheed images and intesity oscillation are collected by computer system . it showed that the gasb film prepared in 400 was amorphous and it became monocrystalline when the temperature rose to 500 . atomic force microscope ( afm ) was applied to analyse the surface morphology of the films which were grown in diffrent growth rates or substrate temperature . the analysis were compared to simulation results . the experiment results indicated it was easy to form clusters when the rate of growth is high or
此外,本文通过反射式高能电子衍射( rheed )监测了gasb外延薄膜的生长,利用rheed强度振荡的计算机采集系统实现了rheed图像和rheed强度振荡的实时监测。实验发现在400生长的gasb薄膜为非晶态,温度升高到500薄膜转变为单晶。利用原子力显微镜对不同生长速率和衬底温度生长的gasb薄膜的表面形貌进行观察分析,并与模拟结果进行比较。
