Advanced CVD technology for 2D materials: graphene and transition metal di-chalcogenides
Graphene, one of the most important two dimensional (2D) materials, has been attracting increasing interest and new applications in nano-scale electronic and photonic applications through the unprecedented electronic and optical properties it offers. However, the zero bandgap of graphene has restricted its use in some optoelectronic applications. Recently, transition metal dichalcogenides (TMDCs), two-dimensional layered materials, such as MoS2, MoSe2, WS2 and WSe2 have become a noteworthy complimentary material to graphene sharing many of its properties. They may however offer properties that are unattainable in graphene since TMDCs offer tuneability allowing a bandgap transition from indirect to direct with the single layer. This has led to use of TMDCs in applications such as transistors, photodetectors and electroluminescent devices. Chemical vapour deposition (CVD) technology has the advantage of offering conformal, scalable, and controllable thin film growth on a variety of different substrates. In this talk we describe our recent development in 2D materials, in particularly graphene and TMDCs, by the CVD technology and discuss their potential applications.

Abstract

Graphene, one of the most important two dimensional (2D) materials, has been attracting increasing interest and new applications in nano-scale electronic and photonic applications through the unprecedented electronic and optical properties it offers. However, the zero bandgap of graphene has restricted its use in some optoelectronic applications. Recently, transition metal dichalcogenides (TMDCs), two-dimensional layered materials, such as MoS2, MoSe2, WS2 and WSe2 have become a noteworthy complimentary material to graphene sharing many of its properties. They may however offer properties that are unattainable in graphene since TMDCs offer tuneability allowing a bandgap transition from indirect to direct with the single layer. This has led to use of TMDCs in applications such as transistors, photodetectors and electroluminescent devices. Chemical vapour deposition (CVD) technology has the advantage of offering conformal, scalable, and controllable thin film growth on a variety of different substrates. In this talk we describe our recent development in 2D materials, in particularly graphene and TMDCs, by the CVD technology and discuss their potential applications.
