Job description

Offer DescriptionProject PI: Prof. dr. hab. George FytasFixed-term contract for 3 years.In this project, we aim to investigate how the elasticity, photo-thermal effects, and hypersonic stopbands (all polarizations) can be tuned by architected GNP, discovering new metamaterial properties and ambient and high hydrostatic pressure. Establishing a reliable predictive power will open new application pathways of soft-matter-based high-frequency phononics.To realize this vision, we will employ state-of-the-art GNP synthesis and experimental tools (e.g., Brillouin light scattering, frequency domain thermoreflectance, and rheometry) in close international and multidisciplinary collaboration between five research groups from Poland, Germany, Spain, Greece, and the United States.We will verify the research hypotheses: (i) High-frequency elasticity should deviate from a continuum-level behavior depending on graft conformation and GNP internal structure and packing. (ii) The subwavelength hypersonic stopband (hybridization) should display a complex dependence on grafting density, lattice constant, and architecture. (iii) The amplification of narrow-band metamaterial absorption in the visible regime and modulated thermal transport should relate to the phoxonic features of GNPs.The advancement of a new field creates knowledge in physics and material engineering and challenges material nanofabrication and characterization: (1) Strong, robust, and low-density nanostructured functional materials are of paramount importance for a wide range of applications comprising microelectronic, photonics, nano-electro-mechanical systems, nanofluidics, biomedical imaging, GHz signal processing in 5G and 6G technologies. (2) A detailed understanding of phonon propagation in soft nanostructures is a precondition to accessing fundamental concepts such as micromechanics, tunable hypersonic phononic stopbands, heat management, and phonon-photon interactions. Controlling the elusive flow of heat is a complex challenge across multiple materials, length scales, and devices. The realization of performance enhancements reducing inorganic core content in one-component hybrid materials will have an environmental (recycling) impact. (3) Know-how transfer between the research groups and foremost to young scientists.In particular, the postdoctoral researcher will be responsible for:

• Development of the experimental setup for Brillouin light scattering (BLS) experiments under high pressure.
• BLS evaluation of elastic properties of samples under varied external conditions.
• Day-to-day reporting, manuscript writing, and public dissemination of results.
• Collaboration with the project partners, short-term internships in Barcelona and Mainz.
