Zn dopent may change the crystal structure while the surface morphology becomes rough . and the band gap remains high . so the hydrophilicity of the thin film decreased 本工作表明使用喷雾热解法可以有效的实现tio :镀膜玻璃的制备,以及薄膜的金属离子掺杂改性。
There exists a strong correlation between initial surface morphology prior to ht growth and ht gan growth mechanism and eventual threading dislocation density in epilayers 发现高温生长前样品的表面状态对随后生长的gan生长机制及最终外延层中的位错密度有很大影响。
Sem and sfm were used to observe the surface morphology of the membranes . after grafting modification , the surface of the plla membrane became rougher than the control membrane 采用sem和sfm考察了改性前后材料表面形貌的变化,结果表明接枝改性使得材料表面的粗糙度增大。
The wearing resistance , microstructure , worn surface morphology and hardness change in wearing end - face and non - wearing end - face of cr - mn - cu alloy white cast iron were tested and analyzed 摘要对铬锰铜合金白口铸铁的耐磨性、无磨损端面及磨损端面的微观组织、磨损形貌及硬度进行了试验和分析。
When the droplets were in large diameter , the surface morphology would be more rough and heterogeneous . the surface morphology would be porous when the droplets were too small 过大的液滴使薄膜表面不均匀,液滴过小又会使薄膜表面形成孔洞,只有液滴直径在一定范围内制备的薄膜才能满足要求。
The effect of electrolyte and operating parameters on surface morphology and al2o3 content in coating was investigated in detail by scanning electron microscopy and spectrophotometric determination 采用分光光度法测量镀层中al2o3含量,研究了镀液组成和各工艺参数对表观形貌及al2o3复合量的影响。
Besides , we get further explaination on this phenomenon by afm and sem . the surface morphology of plct ferroelectric thin films was studies by afm combined with other analysis techniques ( for example sem ) 通过扫描电子显微镜( sem )和原子力显微镜( afm )对薄膜的表面形貌的观察,对这一现象进行了解释。
Surface morphology and composition of the a1 film were characterized with field emission scanning electron microscopy ( fesem ) and energy dispersive spectroscopy ( eds ) to optimize a1 film growth conditions 利用场发射扫描电镜( fesem )及能量散射谱( eds )分析仪对沉积的铝层进行了表面形貌的表征和化学组分的分析。
In this paper , the characteristics and formation mechanism of this periodic surface microstructure are reviewed , and the application of this theory in earth surface morphology formation is also introduced 综述了对这种周期性表面微结构的特点及其形成机理的研究,并介绍了该理论在地壳表面形貌形成机理研究中的应用。
The experiments show : growth temperature is one of the key growth parameter by which the surface morphology , alloy composition , crystalline quality , mobility and carrier concentration are influenced 实验表明:生长温度是一个重要的生长参数,它对外延层的表面形貌、组分、结晶质量、迁移率、载流子浓度有着很大影响。
