Hybrid materials, consisting of diverse materials combined in various configurations, exhibit intriguing opto-electronic properties and are a focal point of research in functional…
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…
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…
