Pulsed Laser Deposition (PLD)

控制复杂的功能和量子材料的电子性质是固体物理领域的热门研究方向。复合氧化物的静态和动态电子性质为探索新的功能提供了一个很有希望的基础，例如用于未来的信息技术或传感。在基本层面上，在氧化物界面上出现了令人着迷的现象，例如新出现的、可控的磁性或铁电状态。所应用的设备旨在使超薄氧化物薄膜和混合氧化物异质结构能够以原子尺度的精度沉积。相互作用现象的研究将在这些复杂的电子系统上进行。为了制造这种具有精确单层控制的材料体系，需要一个脉冲激光沉积(PLD)系统来进行靶向样品的制备。PLD方法将为申请人所在组中的复合氧化物建立一种新的生长方法，并理想地补充现有的分子束外延系统(Oxid-MBE)。现场样品转移选项能够生成新型复杂氧化物杂化化合物，并对其进行全面的结构和化学表征。通过这种方式，物理系和新启动的SFB1432在主题上得到了加强，并创造了新的合作机会-在康斯坦茨大学和(跨地区)。

Controlling the electronic properties of complex functional- and quantum materials is a highly topical research direction in the field of solid state physics. Both the static and dynamic electronic properties of complex oxides provide a promising basis to explore novel functionalities, e.g. for future information technology or sensing. On a fundamental level, fascinating phenomena open up at oxide interfaces, such as newly emerging and controllable magnetic or ferroelectric states.The equipment applied for is intended to enable the deposition of ultra-thin oxide films and hybrid oxide heterostructures with atomic-scale precision. The investigation of interacting phenomena will be carried out on these complex electronic systems. In order to produce such material systems with precise monolayer control, a pulsed laser deposition (PLD) system is required for targeted sample preparation. The PLD method will establish a new growth method for complex oxides in the applicant’s group and ideally complement the existing molecular beam epitaxy system (Oxide-MBE). An in-situ sample transfer option enables the generation of new types of complex oxide hybrids and their comprehensive structural and chemical characterization. In this way, the physics department and the newly started SFB1432 are thematically strengthened and novel opportunities for cooperation are created – at the University of Konstanz and (trans-) regionally.
