Jobbeschreibung

The Joint Research Group for Hybrid Material Systems is a cooperation between the Helmholtz-Zentrum Berlin and the Humboldt-Universität zu Berlin. The focus of our research lies on modern semiconductors and their interfaces in devices. We are using synchrotron-based investigation methods to reveal the electronic structure (photoelectron spectroscopy).As a scientist in our team you will perform research that encompasses the study of the electronic structure of modern semiconductor thin-films and their interfaces with angle-resolved ultraviolet photoelectron spectroscopy (AR-UPS) and XPS. Moreover, you will further develop operando AR-UPS,CFS-YS,NEXAFS,and XPS.

Your Tasks

• You analyse the chemical and electronic structure of modern semiconductors and interfaces (AR-UPS,CFS-YS, NEXAFS, and XPS).
• You plan and conduct experiments (in labs and at synchrotron radiation sources).
• You cooperate with other researchers, particularly doctoral students.
• You take on research and project management tasks.
• You curate data andprepare publications.

Your Profile

• Completed doctoral degree in physics or chemistry
• Expertise in semiconductor carrier and excitation dynamics
• Demonstrated experience in research onperovskites and/or organic semiconductors
• Demonstrated experience in global and deconvoluted datafitting, programming in Python and Matlab, as well as electronic structure modeling
• Intercultural competence and excellent communication skills
• Excellent proficiency in either German or English (C1), with good proficiency in the other language (B2)

Your Benefits at HZB

At Helmholtz-Zentrum Berlin, you will benefit from a collaborative international environment, state-of-the-art research facilities, and a wide range of benefits to support your scientific career:

• 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 Center 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 the 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 24 months. 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.

Climate change poses serious challenges to the whole world. At Helmholtz-Zentrum Berlin, we are researching materials for a climate-neutral future. 1400 employees from all over the world are working together at HZB towards this goal. Join us, and help us achieve it! Learn more about HZB on our website.
