HL 37: Focus Session: Growth, Properties and Application of Epitaxial Graphene (joint session DS/HL/O)

Donnerstag, 4. April 2019, 09:30–12:45, H32

Graphene is the only 2D material, which up to now can be grown almost defect-free on large scales. The application of epitaxial concepts has turned out as a breakthrough in graphene research, because it provides control over the interface and surface structure of epitaxial graphene (EG) layers with atom-scale precision and in an efficient and technologically compatible way. A wide variety of physical phenomena have been observed in graphene-based structures, including topologically protected states, high charge carrier mobility, electron correlation or superconductivity. This versatility makes EG an ideal platform for the integration of graphene-based structures into electronic applications.

This Focus Session aims at fostering the cooperation between groups working in the field of the synthesis, characterization and integration of systems based on large, structurally well-ordered graphene layers. For this purpose it collects state-of-the-art contributions to all involved aspects of EG research, from the growth, functionalization and characterization to the integration of EG-based materials.
