The Leibniz-Institut für Kristallzüchtung invites applications for a
Post-doctoral Researcher (m/f/d)
position. The successful candidate will contribute to an exciting research program focused on
“Improving the thermo-optical properties of Ge single crystals for Infrared applications”
The demand for infrared (IR) optical technologies is rapidly increasing across various sectors. At present, Germanium (Ge) single crystals are widely used as key lens materials due to their high refractive index and low dispersion. However, Ge lenses face significant challenges arising from their high thermo-optical coefficient, which leads to optical aberrations and image degradation at elevated temperatures. In this AiF/ZIM project, funded within the framework of BMWK 2+2, the aim is to develop Ge crystals with engineered properties to enhance the opto-thermal stability. Based on these materials, optical lenses will be fabricated in collaboration with an industrial partner.
Position Overview
The position focuses on advanced research in Ge crystal growth with particular emphasis on specific doping processes. State-of-the-art Czochralski (Cz) pullers are available within the research group for this purpose. Part of the work will include characterization of the crystals to assess their structural and optical properties. The project will be carried out in co-operation with industry and international partners, requiring regular scientific exchange to ensure its success. This will also include joint meetings as well as publishing research findings in peer-reviewed journals and conferences. Additional responsibilities may include mentoring graduate and undergraduate students and contributing to the development of grant proposals and project reports.
Requirements:
- PhD degree in materials science, physics or closely related field
- Strong background in semiconductor materials and crystal growth techniques
- Experience with structural, electrical, and/or optical characterization techniques
- Self-management and active collaboration in a team of scientists, technicians and students
- Very good knowledge in English language; A basic knowledge of German is beneficial
Desirable Qualifications/Experience:
- Practical experience in the Cz-growth of bulk crystals
- Knowledge of defect analysis, doping control in semiconductors
- Experience in collaborating with industry
What we offer
- A stimulating, modern and multidisciplinary laboratory work environment
- Comprehensive training in our crystal growth processes
- Contributing to state-of-the art research/process development, including leading growth experiments
- Full-time position, limited to two years with the option of part-time work
- Payment in accordance with the collective agreement for the public sector (TVöD Bund, classification is based on qualifications and experience) including the usual social benefits (30 vacation days with a 5-day week, company pension scheme) and a company ticket allowance.
- Individual opportunities for internal and external training
