Post Doctoral Researcher (f/m/d) K25/26

The Leibniz-Institut für Kristallzüchtung (IKZ) is a leading research institution in the area of science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for urgent societal challenges (e.g. communication, artificial intelligence, climate protection, health etc.). by modern electronic & photonic technologies. The work covers the full spectrum from basic over applied research up to pre-industrial development and is performed in collaboration with national and international partners from university, academy and industry.

The institute is part of the Forschungsverbund Berlin ( https://www.fv-berlin.de/ ) and a member of the Leibniz Association www.leibniz-gemeinschaft.de . You can find more details on the institute webpage: www.ikz-berlin.de . The Leibniz-Institut für Kristallzüchtung currently offers a  Post Doctoral Researcher (f/m/d) position for the topics of “2D electronics, memory transistors, and chemical vapor deposition”.

This project (funded by the ERC) targets to establish 2D phyllosilicates as a versatile insulator class in 2D electronics, with a focus on memory transistors and reconfigurable hardware. A particular focus of the position would be on the growth of 2D semiconductors on monocrystalline phyllosilicate substrates, mainly via salt-assisted vapor-liquid-solid chemical vapor deposition, as well as establishing a growth route for phyllosilicate thin films .

The tasks would also go in the direction of proof-of-principle integration of the grown interfaces and layers into devices as field effect transistors, memory transistors , and more elaborate reconfigurable logic blocks . The successful candidate will contribute to the development of the 2D phyllosilicates as a material class , and with special focus on benchmarking their performance in advanced electronic applications.

The candidate will actively work on the development of an ambient/low-vacuum Ar-flow CVD setup , growth protocols, and routes for transfer (on 1 cm2 basis) of the films and interfaces into various device architectures. The candidate will also contribute to the electrical characterization and proof-of-principle device design . The position will expect from the candidate to independently coordinate their work and especially to actively participate in project-specific collaborations with the project partners at TU Wien, Uni BW Munich, Trinity College Dublin, Stanford University, and others.

Requirements: PhD in Physics, Materials Science, or a related field , with a focus on at least one of the fields: 2D semiconductors, 2D electronics, CVD growth of 2D materials, bulk growth of van der Waals crystals. Advantageous: Experience with salt-assisted CVD process for 2D semiconductor growth, 2D flake transfer (PDMS, PC, SiN, Au), FET integration, photolithography, electrical characterization (transfer, stability, hysteretic device behavior, etc).

Strong data-analysis skills preferably using Python and/or Matlab. Equipment/infrastructure-wise advantageous: Familiarity with vacuum systems, with tube furnaces, with controller design (python/LabVIEW), clean-room facilities (spin coating, mask aligning, laser writing), AFM/Raman characterization. Experience in drafting and writing scientific manuscripts is required, as well as the track record that reflects this claim (preferably experience in using LaTeX).

Self-management and ability to actively and self-driven contribute to the research team, and to coordinate tasks of technicians and students. Proficiency in English (written and spoken). What we offer The position is initially a fixed-term position through April 28, 2028. Payment is according to TVöD Bund (E13) (Treaty for German public service) including the usual social benefits (30 vacation days in a 5-day week, flexible working hours).

The IKZ is an equal opportunity employer and actively supports reconciliation of work and family life. There is equality for applicants of all gend
