摘要

研究了ne离子辐照锐钛矿TiO2/SrTiO3薄膜的微观结构演变。辐照后在TiO2/SrTiO3界面附近形成缺陷剥落层。缺陷在TiO2/SrTiO3界面处的积累导致SrTiO3表面形成连续的界面非晶层。这两种观察结果都归因于缺陷与界面的相互作用。目前的研究结果表明,两种不同氧化物之间的异质外延界面可以作为吸收辐射诱导缺陷的有效汇。

Interface-enhanced defect absorption between epitaxial anatase TiO2 film and single crystal SrTiO3

The microstructural evolution of Ne-ion-irradiated anatase TiO2/SrTiO3 films was investigated. A defect denuded layer formed in the TiO2 film near the TiO2/SrTiO3 interface after irradiation. The accumulation of defects at the TiO2/SrTiO3 interface led to the formation of a continuous interfacial amorphous layer on SrTiO3. Both observations are attributed to the interaction of defects with the interface. Present results reveal that a hetero-epitaxial interface between two different oxides can act as an effective sink to absorb irradiation-induced defects.

期刊介绍: Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
