Leveraging Plasmonic Hot Electrons to Quench Defect Emission in Metal -- Semiconductor Nanostructured Hybrids: Experiment and Modeling
Kritika Sharu, Shashwata Chattopadhyay, K. N. Prajapati +1
Modeling light-matter interaction in hybrid plasmonic materials is vital to their widening relevance from optoelectronics to photocatalysis. Here, we explore photoluminescence from…
Mobility enhancement in CVD-grown monolayer MoS2 via patterned substrate induced non-uniform straining
Arijit Kayal, Sraboni Dey, Harikrishnan G. +3
The extraordinary mechanical properties of 2D TMDCs make them ideal candidates for investigating strain-induced control of various physical properties. Here we explore the role of…
Hyperspectral imaging with Raman scattered photons: A new paradigm in Raman analysis

Surface enhanced Raman spectroscopy, is a technique of fundamental importance to analytical science and technology where the amplified Raman spectrum of analytes is used for chemic…
Selective Enhancement in Phonon Scattering leads to High Thermoelectric Figure of Merit in ZnO -- Graphene Oxide Core-shell Nanohybrids
Soumya Biswas, Saurabh Singh, Shubham Singh +5
ZnO is a promising candidate as an environment friendly thermoelectric (TE) material. However, the poor TE figure of merit (zT) needs to be addressed to achieve significant TE effi…
Tailoring Infrared Absorption and Thermal Emission with Ultrathin-film Interferences in Epsilon-Near-Zero Media
Ben Johns, Shashwata Chattopadhyay, Joy Mitra
Engineering nanophotonic mode dispersions in ultrathin, planar structures enables significant control over infrared perfect absorption (PA) and thermal emission characteristics. He…
Thickness induced metal to insulator charge transport and unusual hydrogen response in granular palladium nanofilms
Dharmendra K. Singh, Praveen S. G., Adithya Jayakumar +4
This work reports a systematic study of the evolution of charge transport mechanism in granular ultra-thin films of palladium of thickness varying between 6nm and 2nm. While the fi…
