Pulsed Laser Deposition (PLD)

控制复杂功能和量子材料的电子特性是固体物理领域的一个热门研究方向。复合氧化物的静态和动态电子特性为探索新功能提供了有希望的基础，例如未来的信息技术或传感。在基本层面上，氧化物界面上出现了迷人的现象，例如新出现的可控磁性或铁电态。该设备旨在实现原子级精度的超薄氧化膜和杂化氧化异质结构的沉积。相互作用现象的研究将在这些复杂的电子系统上进行。为了生产具有精确单层控制的这种材料系统，需要脉冲激光沉积（PLD）系统来制备目标样品。PLD方法将在申请人的群体中建立一种新的复合氧化物生长方法，并理想地补充现有的分子束外延系统（Oxide-MBE）。原位样品转移选项可以生成新型复杂氧化物杂化物，并对其进行全面的结构和化学表征。通过这种方式，物理系和新成立的SFB1432在主题上得到加强，并在康斯坦茨大学和（跨）地区创造了新的合作机会。

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.
