Postdoc in Wood Photonics
Kungliga Tekniska högskolan, Skolan för teknikvetenskap
KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as in architecture, industrial management, urban planning, history and philosophy.
The position is at the Department of Applied Physics, and part of the multidisciplinary ERC-project WOOD-NANOTECH at the Wallenberg Wood Science Center (WWSC) at KTH. WWSC is a research center with focus on new materials from trees. The mission of the center is to create knowledge and build competence that can form the basis for an innovative future value creation from forest raw material.
Wood is the most successful bio-based material throughout history for structural applications owing to its excellent mechanical properties and natural abundancy. Its mechanical superiority is fundamentally derived from its hierarchical structuring based on aligned cellulose fibers. Recently it was demonstrated in KTH that one can create optically transparent wood by infiltrating polymer into a wood-derived cellulosic template [Biomacromolecules 17, p. 1358 (2016)]. Adding transparency and other optical properties and functions to wood provides a new dimension to a traditionally load-bearing material. Besides aesthetic transformation of wood, application examples include light-transmitting façades and panels, solar cells, light-emitting surfaces, electrochromic windows for homes or vehicles, to name a few.
The project investigates fundamental optical properties of transparent woods, as well as transparent woods doped with quantum dots, dyes, plasmonic nanoparticles, etc. Sample preparation will be carried out by other members of the team at the Wallenberg Wood Science Center. Nano-characterization and optical measurement facilities in our Electrum Laboratory will be extensively used to study wood nanostructures and correlate the structure and chemical composition to observed optical properties. Optical imaging and spectroscopy measurements can be in the visible, near-infrared, and possibly mid-infrared spectral ranges. The candidate participate in team activities related to sample preparation and installation of characterization setups. Some numerical modelling of light scattering behavior in transparent wood is also expected.
This postdoctoral position is a full-time employment position for one year with a possible one-year extension. The starting date is open for discussion, preferably October 2017.
The applicants should have a PhD degree obtained within last three years, in a subject relevant for the research, such as optics/photonics or material physics. Candidates without a PhD degree but expected to defend before the project starting date are also welcome to apply.
The candidate is supposed to have adequate knowledge on optics, optical phenomena of materials, and is familiar with basic optical spectroscopy and imaging techniques. Experience in nanomaterial fabrication and characterization, and/or numerical electromagnetic modelling is a plus. Background in optical waveguide theory and/or applications is an advantage.
The applicant must show proven capability to publish in renowned international journals. He or she must be strongly motivated, able to work independently or together with team members. Project management skills and good communication skills are merits.
