Since the first isolation of graphene in 2004, a great progress has been made on its synthesis techniques from chemical exfoliation, chemical vapor deposition (CVD) to bottom-up organic synthesis. We have been working on the CVD growth of high-quality graphene and its 2D hybrid materials since 2008. By rationally designing the growth catalysts and the elementary steps in the growth process, we have been able to make a precise control of graphene layer number, stacking structures, doping, wrinkle structures and even bandgaps by hybridization with different 2D materials. This talk will present our recent progresses along this direction. A particular focus will be laid on growing graphene on groups IVB-VIB early transition metal foils and wide-gap semiconducting substrates such as h-BN and high k strontium titanate together with the designed growth of mosaic graphene, a periodic in-plane hybrid structure with other 2D materials.
