In-situ LEEM investigation of the growth of hexagonal boron nitride on metal surfaces — •Janina Felter, Markus Franke, and Christian Kumpf — Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, 52425 Jülich, Germany, and Jülich Aachen Research Alliance (JARA)-Fundamentals of Future Information Technology, Germany

Hexagonal boron nitride (hBN) is a prominent and frequently studied member of the family of two-dimensional (2D) materials. Due to its structural and electronic properties, in particular its insulating nature, it is of highest interest as part of hetero-epitaxial systems in conjunction with other 2D materials or organic thin films. However, the production of high quality hBN monolayers and organic thin films on hBN necessitates a deep understanding of nucleation and growth of these materials. Here, we present a detailed in-situ and real-time study of the growth of hBN monolayers on Cu(111) using Low-Energy Electron Microscopy (LEEM). We correlate the results with structural information obtained by µ LEED and discuss the influence of substrate temperature, growth rate and movement of step edges.
