Visualization of Physical Properties of 2D Layers using Low Energy Electron Microscopy

BildCopyright: Prof Dr. Altman

Crystalline surfaces are convenient templates for the growth of ultrathin films and atomically thin two-dimensional (2D) layers by physical and chemical vapor deposition methods.  However, the presence of the substrate template, in many cases, can influence the physical properties and functionality of the 2D layers that make them interesting materials.  

In this talk, I will describe how the visualization of supported 2D layers using low energy electron microscopy and highly spatially resolved micro-low energy electron diffraction provides important insights about supported 2D layers. This will cover insights about strain relief mechanisms and large commensurate Moiré superlattices in 2D Dirac and nodal line semimetals, graphene on Cu(111) and Cu2Si on Si(111), respectively, and polymorphism and reactivity of FeO on Pt(111).
