Material science is currently experiencing a minor revolution due to the emergence of 2D materials. In this regard, the primary contributor has been graphene. However, several other materials of similar or complementary nature are now being studied extensively.
For 2D materials to meet the high expectations reliable large area production methods are needed. Chemical vapour deposition (CVD) is the method of choice, and has indeed proven to be an extremely versatile tool for producing high quality films of a plethora of compounds.
Here we report on the synthesis of hexagonal boron nitride (h-BN) and molybdenum disulphide (MoS2) from solid precursors. The films/crystals are characterised primarily using Raman spectroscopy and atomic force microscopy (AFM) and show mono- to few-layer structures. Initial attempts to build hetero-structures with graphene have been made either by direct “on-to” growth or through transfer procedures. At Newtec Engineering A/S we see great potentiel for such materials to be implemented in e.g. sensing devices and a FET-based platform is currently being developed.
Bjarke received his bachelor degree in 2010 working on hydrothermal synthesis of ZrO2 nanoparticles. After a year away from academia, teaching public school and gymnasium, he initiated his master studies and became familiar with the Organic Surface Chemistry group. They were at that time starting to look into graphene and under their supervision he set up equipment for chemical vapour deposition with the aim of growing high quality graphene on metal substrates. He received his master degree in early 2013 and soon thereafter started working at Newtec Engineering A/S in Odense, with whom he is now doing an industrial PhD.
