  2. 16. Microscopic Theory of Exciton Dynamics in Two-Dimensional Materials

    Author : Samuel Brem; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exciton-phonon interaction; van der Waals materials; relaxation dynamics; excitons; 2D materials; density matrix formalism;

    Abstract : Transition Metal Dichalcogenides (TMDs) present a giant leap forward towards the realization of nanometer-sized quantum devices. As a direct consequence of their truly two-dimensional character, TMDs exhibit a strong Coulomb-interaction, leading to the formation of stable electron-hole pairs, so-called excitons. READ MORE

  4. 17. Integration of Two-Dimensional Materials for Electronics and Photonics

    Author : Arne Quellmalz; Kristinn Gylfason; Frank Niklaus; Cedric Huyghebaert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Two-dimensional (2D) materials with a thickness on the atomic scale promise to continue the trend of increasing performance in electronics, photonics, and sensing. However, despite record-breaking demonstrations of individual devices, the commercial exploitation of 2D materials is still limited. READ MORE

  5. 18. 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

  7. 20. P-type ATPases studied by electron microscopy and two-dimensional crystallization

    Author : Kenneth Yijing Xian; Karolinska Institutet; Karolinska Institutet; []
    Keywords : electron microscopy; ion transport; membrane protein; P-type ATPase; two-dimensional crystallization;

    Abstract : Electron microscopy and two-dimensional crystallography have been used to study the molecular structures of the porcine renal Na+,K+-ATPase and the porcine gastric H+,K+-ATPase. In addition, morphological changes have been observed with electron cryomicroscopy from tubulovesicles in porcine gastric mucosae. READ MORE
