New Photovoltaic and Plasmonic Avenues to Amplify Light Matter Interaction at the Atomic Scale

Dr Arindham GhoshThe enormous impact of graphene on both fundamental science and potential device applications has rejuvenated interest in other layered materials as well, where individual atomic or molecular layers interact weakly through the Van der Waals force. Unfortunately, in spite of great promise in electronic applications, most of these materials couple weakly to electromagnetic radiation when their thickness is reduced to atomic or molecular scales, and hence much of their optical or opto-electronic capabilities remain unexploited. Here, we will describe some of the recent breakthroughs in sensitizing atomically thin membranes, in particular graphene, to electromagnetic radiation. Two specific technologies will be discussed in detail. First, a photovoltaic route involving multi-component two-dimensional hybrids obtained via vertical stacking of different layered materials will be described in detail. We will show how such hybrid heterostructures of atomically thin membranes with clean interfaces promise devices that combine advantages of ultimate miniaturization and multiple opto-electronic functionality. In the second part of the talk, a novel nanoplasmonic route with vertically stacked graphene - metal nanoparticle dimers will be demonstrated, which emerges as a highly promising platform for high speed color-selective photo detection.

Dr Ghosh was awarded the Young Nanoscientist India Prize at the Nanotechnology Forum held on 16th April 2015. The NT Forum was formed in 2014 to encourage research in the field of Nanotechnology in India and acknowledge outstanding achievements in this field. The Chairman of the Prize selection committee is Bharat Ratna Professor C.N.R. Rao – Honorary President, JNCASR.

The objectives of the Nanotechnology Forum are :-

• Promote research in the fabrication and characterisation of nano materials and structures in physical or bio nanotechnology

• Motivate young Indian researchers in the field of nanotechnology

• Increase scientific exchange between India and United Kingdom
