Materials have always been at the heart of new inventions and, semiconductor industry is not an exception in this case. Two-dimensional (2D) materials are further enriching the available atlas of such novel materials. After the discovery of graphene in 2004, hundreds of other 2D materials are being explored owing to their distinct structures which lead to exciting properties and applications, unseen in other dimensions. Graphene and transition metal dichalcogenides (TMDs) based on molybdenum and tungsten have shown great promises for future technological applications including Internet of Things. Moreover, intriguing desired properties can be obtained by making hybrids and heterostructures of suitable 2D materials. Chemical vapor deposition (CVD) is the technique with a potential for scaling up the production of good quality 2D materials.

In this talk, I will give a brief introduction to 2D materials like graphene and molybdenum disulphide (MoS2) with emphasis on their large-scale production using CVD method. The open challenges for integrating these materials, especially graphene, into process technology will be discussed.
