2D Layers as Substrates for New Materials

2D Layers as Substrates for New Materials

Title: 2D Layers as Substrates for New Materials.
When: Thursday, May 18, (2017), 14:30.
Place: Departamento de Física de la Materia Condensada, Facultad Ciencias, Module 3, Seminar Room (5th Floor).
Speaker: Thomas Michely, Physikalisches Institut, Universität zu Köln, Germany.

Three examples for the use of 2D layers as substrate for the growth of new materials are given.

First, a new on-surface synthesis method is reported that enables the growth sandwich molecular nanowires. The synthesis is based on the use of Gr as an inert substrate and relies on the simultaneous deposition of rare earth metal atoms and organic ligands. These nanowires are a new class of 1D magnetic entities, distinct from 0D single molecule magnets and 2D organo-metallic networks.

Second, we report on the growth and use of hexagonal boron nitride monolayers on Ir(111) as a template for metallic and non-metallic nanoclusters, for holes and for its own decay.

Third, we will show that graphene is a versatile template for the growth of monolayers of transition metal dichalcogenides, enabling to investigate these materials in their pristine state.
