Scientist (f/m/d) of Advanced In-System X-Ray Photoelectron Spectroscopy During the MBE Growth of Oxide Heterostructures on Semiconductors
Reference No.: QM 2025/3
In the Institute IFOX at HZB, we work on functional oxide thin films and nanostructures combined with semiconductors for energy-efficient information technology. We focus on material synthesis, detailed structural characterization using advanced methods, and on device properties for neuromorphic computing applications.You will work in the framework of the ERC Advanced Grant LUCIOLE (Layering, Understanding, Controlling, Integrating Ferroelectric Polar textures on Silicon).
You will investigate the different steps of the growth of ferroelectric oxides such as BaTiO3 (and other compositions) on Si, Ge and SiGe substrates. Thanks to a XPS tool connected to the MBE cluster, the growth (including the very first steps of surface passivation) will be studied “in-system”, without air break. The information gained will allow to engineer the interfaces with the substrate and between layers in superlattices. The postdoctoral scientist will work closely with the scientists performing the molecular beam epitaxy.
Your Tasks
- X-ray photoelectron spectroscopy characterization of oxide heterostructures on semiconductors
- In system XPS investigation during MBE growth for interface and material engineering
- Synchrotron experiments by HAXPES, PEEM, XRD
- Supervise Master and/or PhD students
- Presentation at international conferences and scientific publications of experimental results
Your Profile
- Completed PhD in Physics, Chemistry or Materials Science.
- Extended experience in X-ray photoelectron spectroscopy (at least 2 years).
- Experience in the field of oxide thin films.
- Experience in the field of ferroelectrics is a plus
Your Benefits at HZB
- a climate-neutral future in cooperation with leading international researchers
- Commitment to diversity and sustainability through an inclusive working environment, promotion of diversity sensitivity and implementation of sustainable and climate-neutral methods
- Career-enhancing networking opportunities and individual mentoring and support from the HZB Graduate Center and HZB Postdoc Office
- Attractive remuneration through payment according to TVöD Bund
- 30 days holiday/year
- Extensive additional benefits, such as company pension plan (VBL), subsidy for public transport (Deutschlandticket Job) and company sports programmes
- Good work-life balance through counselling services on family and career and flexible working time models: Flexitime, part-time, hybrid working
- And a team that is looking forward to meeting you!
Fixed term contract for 24 months. The salary is based on the Collective Agreement for the German Public Service (TVöD-Bund).
