Postdoc (f/m/d) on “Ferroelectric ultra-scaled devices based on topological polar textures”

Postdoc (f / m / d) on Ferroelectric ultra-scaled devices based on topological polar textures

Reference No. : QM / 7

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.

As a postdoctoral researcher, you will work in the framework of the ERC Advanced Grant LUCIOLE (Layering, Understanding, Controlling, Integrating Ferroelectric Polar textures on Silicon).

You will develop 2- and 3-terminal devices integrating ferroelectric polar textures and investigate their electrical behavior.

The electrical manipulation of polar textures under electrical field will be explored. Devices with sub- nm dimensions will be targeted.

In addition to that, you will develop AI-based methods to analyze large amount of data obtained from thousands of devices at wafer scale to unveil behavioral patterns.

The position, first for two years, can be extended up to five years. A permanent position may be granted at the end of the five years if the professional requirements are met.

Your Tasks

• Fabrication of ferroelectric devices (2- and 3T devices); scaling of the dimensions down to sub- nm dimensions using e- beam lithography
• Detailed electrical characterizations of ferroelectric devices
• Investigation of the signature of polar textures in devices
• Investigation of the manipulation of polar textures by an electrical field or by optical means
• Development of AI-based approaches for the investigation of large amount of devices
• Presentation at international conferences and scientific publications
• Supervision of an engineer who will develop lithography and etching processes
• Supervision of Master students

Your Profile

• Completed doctoral degree / PhD in physics or electrical engineering
• Advanced experience in electrical measurements
• Advanced experience in semiconductor devices
• Advanced experience in device fabrication and clean room environment
• Programming skills in python
• Knowledge in AI in big data is a plus
• Very good command of English
• Excellent teamwork skills

Your Benefits at HZB

• A job at one of the 18 Helmholtz centres
• Work in the research environment of the science metropolis Berlin
• The opportunity to contribute together with researchers from all around the world to the development of renewable energies, energy stores and next-gen technologies for a climate-friendly future
• Training programmes, career advice, specific training courses and networking opportunities organised by the Graduate Centre and Postdoc Office
• Compatibility of work and private life through the support of flexible working time models and the option of mobile working, as well as extensive counselling services on family and career
• 39 hours / week and 30 days holiday / year
• Company health promotion and company sports programmes
• Subsidy for public transport (Deutschlandticket Job)
• Company pension scheme (VBL)
• And a team that looks 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).
