Growth Model for Pulsed-Laser Deposited Perovskite Oxide Films

我们在场产出一些 perovskite 氧化物电影生长的特色作为的一个多水平生长模型高在思考观察到精力电子衍射(RHEED ) 和 ellipsometry 学习。模型描述以平台和步边的分发在生长表面的形态学上成熟在期间并且在免职以后的免职，温度， intra 层运输，夹层运输和 Ostwald 的效果。模型的数字结果与试验性的观察与一致很好。

We present a multi-level growth model that yields some of the key features of perovskite oxide film growth as observed in the reflection high energy electron diffraction （RHEED） and ellipsometry studies. The model describes the effect of deposition, temperature, intra-layer transport, interlayer transport and Ostwald ripening on the morphology of a growth surface in terms of the distribution of terraces and step edges during and after deposition. The numerical results of the model coincide well with the experimental observation.
