The talk will be delivered at 3pm on 15^th Sept. in Chemistry Lecture Theatre, followed by a reception in the Nyholm Room. The abstract and a short bio are attached.

Please note that the seminar is in the Chemistry Lecture Theatre 3pm 15th September.

Growth of High-Quality Graphene and Other 2D Materials By CVD

Graphene materials have unique and excellent properties, and they are expected to be used in many fields. Therefore, fabrication of high-quality graphene is very important. Like graphene, other high-quality two-dimensional (2D) materials are essentially important for investigating new physics and properties in the 2D limit, and for many fascinating applications, in particular, electronic and optoelectronic applications. CVD is a powerful method to grow high-quality grains and films of graphene and other 2D materials such as transition metal sulfides and carbides on metal substrates. For example, millimeter-size and extremely small-size single crystal graphene domains and films on Pt and Cu substrates, large-size single-crystal monolayer WS2 domains on Au substrates, and ultrathin carbide crystals on specifically-designed metal substrates can be grown by ambient-pressure CVD. Three-dimensional graphene interconnected framework can also be synthesized by CVD. These CVD-grown high-quality graphene and other 2D crystals have interesting physical properties and applications, such as transparent conducting films, electronic and optoelectronic devices, and superconductivity.
