Recent years have seen an explosion of exciting new quantum materials with diverse electronic and structural properties. These intriguing properties can often be manipulated, for example by strain engineering [1], a rapidly developing area of research opening doors to new fundamental insights and future technologies. An important step in realising this potential is uncovering the electronic structure, for which angle-resolved photoemission spectroscopy (ARPES) is an ideal tool. We in the Electronic Processes in Quantum Materials (EPQM) group use femtosecond time-resolved ARPES, combining pulsed laser sources with cutting-edge spectrometers, to overcome the limitations of traditional ARPES and gain unrivalled access to electronic structure dynamics throughout the Brillouin zone [2].
Currently the EPQM group in the Department of Physical Chemistry offers a PhD Position - Exploring ultrafast dynamics in strained quantum materials.
The aim of this project is to explore the influence of mechanical strain on femtosecond dynamics within the electronic structure in 2D and 1D materials. The successful candidate will use our state-of-the-art trARPES setup delivering 21 eV photons at a repetition rate of 500 kHz [3] coupled to two complementary electron spectrometers [4]. A range of promising quantum materials are proposed as starting points for the project, with room to develop new ideas.
You will be employed at the Fritz Haber Institute of the Max Planck Society in the leafy surroundings of Dahlem in Berlin. You will be part of a close-knit group embedded in the department of Physical Chemistry, where you will have the opportunity to develop your own research interests and spark collaborations with other world-leading research groups. Throughout your project there will be considerable opportunity for international travel, professional networking and transferable skills development.
This fully-funded PhD position is initially limited to 3 years, with the possibility of extension.
Requirements
To be eligible you:
- have (or are about to obtain) a master’s degree in physics or equivalent with excellent academic performance
- have already gained some practical research experience
- ideally have some knowledge of at least one of the following areas: ultrahigh vacuum, photoemission spectroscopy, femtosecond lasers, optics, 2D or quantum materials
- are able to communicate clearly in both written and spoken English
- are highly motivated and bring a team-oriented attitude to your work.
How to apply
Your application should include
- Motivation letter
- Complete CV
- Contact details of at least 2 academic references
Applications for this position are only accepted via our online application portal and will be accepted until March 31st, 2022. We thank all applicants for their interest; however, only those individuals selected for an interview will be contacted.
Fritz Haber Institute
The Fritz Haber Institute (FHI) in Berlin is one of the oldest and most renowned research institutes within the Max Planck Society (MPG), Germany's most successful scientific organization. At the FHI, researchers from all over the world are engaged in basic research in the fields of physics and chemistry at interfaces and surfaces, catalysis research, and molecular physics. The Department of Physical Chemistry focusses on the dynamics of elementary processes in solids and at surfaces, in particular, ultrafast dynamics of electronic and lattice excitations, electron-phonon coupling, interfacial charge transfer, spin dynamics, surface reactions, as well as light-matter interaction at the nanoscale.
At the Fritz Haber Institute we are strongly committed to fairness, inclusion and respect, and strive to foster a friendly and inclusive atmosphere. We encourage applications from people of all backgrounds and identities, particularly from under-represented groups.
Max Planck Society
The Max Planck Society endeavors to achieve gender equality and diversity. Furthermore the Max Planck Society aims to increase the participation of women in research. Therefore, applications by women are particularly welcome. The Max Planck Society is also committed to increasing the number of individuals with disabilities in its workforce and therefore encourages applications from such qualified individuals.
