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

研究小组的核心专长和兴趣是凝聚态物质的动力学过程，主要采用体和薄膜异质结构样品。而散装样品可以由几个组在II。目前，我们没有设备来制造广谱复杂的氧化物外延薄膜，这与器件应用高度相关。外延异质结构还有一个优点，那就是人们通常可以生长出很难（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）是一种独特的用于复杂氧化物材料外延异质结构的系统。采用激光烧蚀工艺来生长具有复杂化学计量的材料薄膜已被证明是非常成功的，并且通常是生长特定（亚稳态）化合物薄膜的唯一方法。LAFIGO对Ionela lindfors - vjoyu博士新开始的研究活动至关重要。此外，它将在卓越计划“量子物质与材料”和最近成立的CRC 1238中形成新的核心
