Abstract<br />
Graphene is a very interesting layered material because <strong>of</strong> its high quality electronic characteristics<br />
which can be tuned by application <strong>of</strong> a gate voltage. However optical absorption property <strong>of</strong><br />
single layer graphene is very poor, and hence most <strong>of</strong> the light (> 95%) gets transmitted. Molybdenum<br />
disulphide (MoS 2 ) is another layered material which is optically active and its bandgap<br />
changes with number <strong>of</strong> layers. In this report we have shown that the hybrid structure <strong>of</strong> graphene<br />
and MoS 2 can be made to integrate their electronic and optical characteristics, and gate tunable<br />
optical response can be induced in graphene.
