The 2D material hexagonal boron nitride (hBN) has attracted strongest interest recently, due to its specific structural and electronic properties. As an insulator (band gap of >5eV) it is a very promising material for hetero-epitaxial systems in conjunction with other 2D materials. In this study, we aim for a deeper understanding of its nucleation and growth, as it is necessary to produce high quality monolayers of hBN. In-situ Low-Energy Electron Microscopy (LEEM) studies enable us to follow the formation of hBN monolayers on metal surfaces by chemical vapour deposition of borazine in real time. We report on the growth of hBN on the Ni(111) surface, and compare with earlier studies performed in our group on Cu(111) and Ag(111).
