Pulsed-laser deposition system

该研究小组的核心专业知识和兴趣是凝聚态物质中的动力学过程，主要采用体相和薄膜异质结构样品。虽然在II.Physikalisches Institut可以通过几个组来生长块状样品，但我们目前还没有设备来制备与器件应用高度相关的广谱复杂氧化物外延薄膜。外延异质结构还有一个优点，那就是人们经常可以生长出很难(甚至不可能)以单晶形式获得的系统。激光烧蚀复合氧化物薄膜外延生长系统(LAFIGO)是一种独特的复合氧化物材料外延异质结系统。使用激光烧蚀方法生长具有复杂化学计量比的材料的薄膜已被证明是非常成功的，通常是生长特定(亚稳定)化合物薄膜的唯一方法。LAFIGO对于Ionela Lindfors-Vrejoiu博士新开始的研究活动至关重要。此外，它还将在卓越倡议“量子物质和材料”以及最近成立的CRC1238中形成一个新的核心

The core expertise and interest of the research group are the dynamical processes in condensed matter, employing mainly bulk and thin film heterostructure samples. While bulk samples can be grown by several groups at II. Physikalisches Institut, currently we have no facility for the fabrication of a broad spectrum of complex oxide epitaxial thin films, which are of high relevance for device applications. Epitaxial heterostructures have also the advantage that one can often grow systems which are very difficult (or even impossible) to obtain in single crystalline form. Laser ablation system for complex oxide thin film epitaxial growth (LAFIGO) is a unique system for epitaxial heterostructures of complex oxide materials. Employing laser ablation processes for the growth of thin films of materials that have complex stoichiometry has proven to be very successful and often the only way to grow thin films of particular (metastable) compounds.LAFIGO is crucial for the newly started research activity of Dr Ionela Lindfors-Vrejoiu. Moreover, it will form a new nucleus in the excellence initiative ''Quantum matter and Materials'', and in the recently established CRC 1238
