PhD student position in Strong coupling between two-dimensional materials and plasmonics

Ref: REF 2017-0184


Department of Physics at Chalmers - home of the Graphene Flagship

Stimulated by major needs and challenges in science and a sustainable society, the ambition of the department of Physics is to foster a creative environment for academic research, learning and outreach. We provide a competitive advantage by linking our top-level international and interdisciplinary academic performance in the areas of material science, nanotechnology and energy research with world-leading industrial R&D&I projects. We address a wide array of experimental, computational, methodological and theoretical challenges, from fundamental physics research, through the development of new materials such as graphene to direct industrial projects generating new inventions. We have a strong learning commitment on all levels from undergraduate to PhD studies where physics meet engineering.

The department is the major part of Gothenburg Physics Centre – a collaboration between four departments at Chalmers and Gothenburg University.

Information about the project
Metal nanoparticles of about 100 nm in size are able to strongly interact with visible light by focusing its electromagnetic energy down to deep subwavelength volumes. This opens up possibilities for manipulating and utilizing light on very small length scales – a subject of intense contemporary research.

This Project aims at studying interaction between 2D material like WS2 and WSe2, metal nanoparticles and photonic waveguides. The idea is to reach strong interaction between excitons in the QD and plasmons in the nanoparticles, manifested in vacuum Rabi splitting with only individual quantum emitter involved. This will enable quantum optical research at ambient conditions.

The Project will be conducted in the Division of Bionanophotonics at Chalmers University of Technology under supervision of Dr. Timur Shegai (for more details see: https://www.chalmers.se/en/departments/physics/research/bionanophotonics/research/Pages/ShegaiGroup.aspx).

The group has a long history of acitivities in nanophotonics, which includes expertise in surface-enhanced Raman spectroscopy, plasmonics for sensing (bio)applications, metasurfaces, optical trapping, fundamental plasmonics and more recently strong plasmon-exciton coupling.

The group is embedded in the Department of Physics at Chalmers University of Technology, which is one of the largest Physics departments within Swedish Universities. Our department has direct access to advanced nanofabrication cleanroom facilities at MC2 as well as to all necessary infrastructure, such as optical and electron microscopy instruments for a smooth run of the project.

Major responsibilities
Fabrication of hybrid nanophotonic devices comprising, 2D materials, metallic nanoparticles and photonic waveguides. Their characterization using optical methods, as well as morphological characterization using electron microscopy and/or atomic force microscopy.

Your major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, both in Swedish and in English. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.

Position summary
Fabrication of hybrid nanophotonic devices comprising, 2D materials, metallic nanoparticles and photonic waveguides. Their characterization using optical methods, as well as morphological characterization using electron microscopy and/or atomic force microscopy.

Full-time temporary employment. The position is limited to a maximum of five years.

Optical microscopy, spectroscopy, nanofabrication, photonics, basic surface chemistry, electron microscopy.

To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field.

The position requires sound verbal and written communication skills in Swedish and English. If Swedish is not your native language, you should be able to teach in Swedish after two years. Chalmers offers Swedish courses.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
