Abstract – Graphene, a hexagonal honeycomb structure of carbon atoms, is attracting much interest for its novel physical

properties as well as its potential as a new material for many applications. Because it is made of a single atomic layer of

carbon atoms, it is the ultimate 2-dimensional system. Many novel physical phenomena such as the fractional quantum

Hall effect, Klein tunneling, and Hofstadter’s butterfly have been observed. Furthermore, owing to its high electron

mobility and superb thermal properties, it is expected to be used in future high-speed, large-integration electronic devices.

The field has extended recently to include other class of 2-dimensional materials including transition metal dichalcogenides

such as MoS2. These materials exhibit a new set of interesting physical phenomena and are expected to complement

graphene in future applications. In this talk, I will review the recent progress in graphene and 2-dimensional materials

research and introduce some future applications possibilities.
