ABSTRACT

• Recently, 2D materials have been intensively studied as emergingmaterials for future electronics, including flexible electronics, phot

and electro-chemical energy storage devices.

• We’ll start ith the basic introduction of 2D materials and ill cov

various aspects related to their synthesis, distinguishing charactepresent and potential applications hile concentrating on their

contribution toards !leaner and "reener #lectronics.

RAPHENE THE RISE OF THE 2D MATERI

• "raphene is an allotrope of carbon in the form of a to-dimensional, atomic-sca

honey-comb lattice in hich one atom forms each vertex. $t is the basic structur

element of other allotropes, including graphite, charcoal and fullerenes.

• (he term graphene first appeared in =>?@ to describe single sheets of graphite

constituent of "raphite $ntercalation !ompounds4"$!s5.
