Postdoc (f/m/d) on Ferroelectric Ultra-Scaled Devices for Topotronics

Reference No.: QM 2026/5

At HZB’s IFOX Institute, we investigate functional oxide thin films and nanostructures in combination with semiconductors for energy-efficient information technologies. Our research focuses on materials synthesis, high-resolution structural characterization, and the development of devices for neuromorphic computing. As a postdoctoral researcher, you will work on the ERC Advanced Grant project LUCIOLE (Layering, Understanding, Controlling, Integrating Ferroelectric Polar Textures on Silicon). You will develop 2- and 3-terminal devices incorporating ferroelectric polar textures in the sub-100 nm range and investigate their electrical behavior as well as the controlled manipulation of polar textures using electric fields. Using AI-based methods, you will analyze large datasets from thousands of devices at the wafer scale to identify characteristic behavioral patterns.

Your Tasks

• Fabrication of ferroelectric devices (2- and 3-terminal devices) and scaling down to sub-100 nm dimensions using e-beam lithography
• Detailed electrical characterization of ferroelectric devices
• Investigation of signatures of polar textures in devices
• Investigation of the manipulation of polar textures by electric fields or optical means
• Use of AI-based approaches to analyze large numbers of devices
• Presentation of research results at international conferences and publication in scientific journals
• Supervision of an engineer developing e-beam lithography and etching processes
• Supervision of Master's students

Your Profile

• PhD in Physics, Electrical Engineering, or a related field
• Extensive experience with electrical measurements
• Extensive experience with semiconductor devices
• Extensive experience in device fabrication and cleanroom environments
• Proficiency in Python
• Knowledge of AI-based approaches for large-scale data analysis is an advantage
• English proficiency at C1 level
• Excellent teamwork and collaboration skills

Your Benefits

At Helmholtz-Zentrum Berlin, you benefit from state-of-the-art research infrastructure, an international and collaborative working environment, and a wide range of opportunities for your professional development:

• The opportunity to contribute to the development of innovative materials and technological solutions for a climate-neutral future in cooperation with leading international researchers
• Flexible working hours and the possibility to work remotely
• Career-enhancing networking opportunities, individual guidance, and support through our Graduate Centre and Postdoc Office
• 30 days of vacation per year and attractive remuneration according to the collective agreement for the public sector (TVöD Bund), plus company pension plan
• Advisory services on family and career matters through our Office for Work & Life
• Subsidy for public transport “Deutschlandticket Job” and exclusive employee discounts
• Relocation support from non-EU countries
• German and English courses for all proficiency levels

Fixed term contract for 32 months (until 31 August 2029). The salary is based on the Collective Agreement for the German Public Service (TVöD-Bund).

We very much want our workplace to be diverse, and welcome applications from people with different backgrounds. It is our mission to promote equal opportunities and to improve women’s representation in the workforce. We are therefore very interested in receiving applications from women. Where the qualifications are met, we will give preference to people with disabilities.
