Researcher in studies of electron dynamics in nanowires using femtosecond photoelectron microscopy - Hiring in process/Finished, not possible to apply

The Division of Synchrotron Radiation Physics (www.sljus.lu.se) is a part of the Department of Physics and has more than 50 employees. The focus of the research is experimental studies of electronic, structural and chemical properties of materials, accelerators for Synchrotron radiation and instruments and methods for Synchrotron radiation. At the Division we use and develop a wide range of Synchrotron- and lab-based techniques, such as X-ray photoelectron spectroscopy/imaging and X-ray diffraction/imaging. We also host one of Sweden's largest facilities for scanning probe microscopy. We are additionally engaged in the development of the MAX IV Laboratory in the fields of beamlines, experimental stations, techniques for Synchrotron radiation and the accelerator systems.

NanoLund (http://www.nano.lu.se), formerly known as the Nanometer Structure Consortium, founded in 1988, supports and coordinates activities within nanoscience and nanotechnology at Lund University. NanoLund is today Sweden’s largest research environment for nanoscience, engaging approximately 250 PhD students and scientists in the faculties of engineering, the natural sciences, and medicine at Lund University. Its vision is to bring together the most creative minds in a world-leading interdisciplinary research environment to help overcome society's grand challenges by pushing the frontiers of nanoscience. NanoLund runs Lund Nano Lab (http://www.nano.lu.se/lundnanolab-2), a state of the art facility for nanofabrication.

Subject description
Electron dynamics play a central role in fundamentally important processes such as chemical reactions, thermal and electrical conduction and light-matter interaction. However, direct studies of moving electrons in nanoscale electrical and optical components are challenging because the electrons dynamics is extremely fast, and it is directly linked to the complex atomic structure of the material.

Nanoscale imaging by PhotoEmission Electron Microscopy (PEEM) using a mobile setup, that can be placed at several specialized laser sources, allow studies of femtosecond and attosecond phenomena with high spatial resolution. This can be correlated to a detailed understanding of chemistry and electronic structure to the few nm level on the very same objects.

III-V semiconductor nanowires constitute a central sample platform which is unique due to its wide range of highly reproducible atomically precise complex lateral and vertical heterostructures. It can be combined with single crystalline metal nanostructures, functional Oxides, 2D materials, and Silicon.

Work duties
The successful candidate is will perform research within the subject area.

More specifically, the work duties include:

• Use and development of time-resolved PEEM in conjunction with both femto- and atto-second lasers.
• Studies of III-V semiconductor nanowires and combinations of semiconductors and metal nanostructures.
• Development of relevant laser systems for these measurements
• Collaboration with experts in nanoscale photonics / electronics, advanced lasers, nanoscale synthesis and characterization is essential.
• The project is mainly intended to be experimental, but will be linked to theoretical research.

This work will be embedded in the NanoLund (www.nano.lu.se) Center for Nanoscience. The successful candidate will interact with experts in manufacturing of semiconductor nanoscale structures and devices to design relevant structures.

The work will be performed in collaboration with several other researchers at the institute as well as Ph.D. students and master students.

Qualification requirements
Applicants must have:

• Very good oral and written proficiency in English.
• Experience of time-resolved PEEM in connection with femto and atto-second lasers
