  2. 21. Microscopic Modeling of Exciton-Polaritons in Two-Dimensional Materials

    Author : Beatriz Ferreira; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exciton-polaritons; 2D materials; diffusion; absorption;

    Abstract : Integrating 2D materials into high-quality optical microcavities opens the door to fascinating many-particle phenomena including the formation of exciton-polaritons. These are hybrid quasi-particles inheriting properties of both the constituent photons and excitons. READ MORE

  4. 22. Investigations of Strong Light-Matter Interactions in Nanophotonic Systems

    Author : Michael Stührenberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoluminescence; strong coupling; localized surface plasmon resonance; bipyramids;

    Abstract : Noble metal nanoparticles can support localized surface plasmon resonances (LSPR), thus behaving as open optical resonators. Outstanding optical properties as well as a subwavelength mode volume make plasmonic nanoparticles a promising platform for enhanced light-matter interactions. READ MORE

  5. 23. Organic Photodiodes : Optical, electric, and morphological aspects of polymer based devices

    Author : Lucimara Stolz Roman; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of semiconducting organic materials as the active layer in optoelectronic devices offers some advantages in processing and new possibilities of device fabrication such as large-area devices. The mechanism of charge generation upon light absorption in organic materials differs from that in inorganic semiconductors. READ MORE
