About
Ram Seshadri is a Distinguished Professor in the Department of Chemistry & Biochemistry and the Materials Department at the University of California, Santa Barbara. He specializes in Inorganic Materials Chemistry and Functional Inorganic Materials. Ram received his PhD in Solid State Chemistry from the Indian Institute of Science in 1995, working with Professor C. N. R. Rao FRS on carbon nanostructures. Following postdoctoral fellowships in Caen, France, with Professor Bernard Raveau, and in Mainz, Germany, with Professor Wolfgang Tremel, he returned to Bangalore as an Assistant Professor at the Indian Institute of Science. In 2002, he moved to UC Santa Barbara, where he has been a faculty member since 2008. His research group aims to develop a fundamental understanding of functional materials that impact everyday life, focusing on the compositional tuning of properties of extended solids through solid solution. His work includes preparing and characterizing new materials, understanding the theory behind functional materials, and developing tools to probe them. Ram serves on the Editorial Committee of the Annual Reviews of Materials Research and is an Associate Editor of the ACS Journal Chemistry of Materials.

Physical Review Letters · 2020 · 938 citations
Recently discovered alongside its sister compounds KV_{3}Sb_{5} and RbV_{3}Sb_{5}, CsV_{3}Sb_{5} crystallizes with an ideal kagome network of vanadium and antimonene layers separated by alkali metal ions. This work presents the electronic properties of CsV_{3}Sb_{5}, demonstrating bulk superconductivity in single crystals with a T_{c}=2.5 K. The normal state electronic structure is studied via angle-resolved photoemission spectroscopy and density-functional theory, which categorize CsV_{3}Sb_{5}…
Design Principles for Enhancing Photoluminescence Quantum Yield in Hybrid Manganese Bromides
Journal of the American Chemical Society · 2020 · 377 citations
Senior authorCorresponding, where a PLQY of 70.8% for a powder sample and 98% for a large single crystal sample is achieved. Our study reveals a generalized method for improving PLQYs in hybrid manganese bromides and is readily extended to designing all varieties of highly emissive hybrid materials.
Physical Review X · 2021 · 243 citations
The recently discovered family of AV 3 Sb 5 (A: K, Rb Cs) kagome metals possess a unique combination of nontrivial band topology, superconducting ground states, and signatures of electron correlations manifest via competing charge density wave order. Little is understood regarding the nature of the charge density wave (CDW) instability inherent to these compounds and the potential correlation with the onset of a large anomalous Hall response. To understand the impact of the CDW order on the elec…

The synthesis and characterization of vanadium-based kagome metals ${\mathrm{YV}}_{6}{\mathrm{Sn}}_{6}$ and ${\mathrm{GdV}}_{6}{\mathrm{Sn}}_{6}$ are presented. X-ray diffraction, magnetization, magnetotransport, and heat capacity measurements reveal an ideal kagome network of V ions coordinated by Sn and separated by triangular lattice planes of rare-earth ions. The onset of low-temperature magnetic order of Gd spins is detected in ${\mathrm{GdV}}_{6}{\mathrm{Sn}}_{6}$ and is suggested to be no…

-PorBTD were found to be 10 times and 2.5 times larger than that of Pt/C, respectively. These COFs also exhibit larger power density and recycling stability in Zn-air batteries compared with a Pt/C-based air cathode. A theoretical analysis demonstrates that the combination of Co-porphyrin with two different BTD ligands affords two crystalline porous electrocatalysts having different d-band center positions, which leads to reactivity differences toward alkaline ORR. The strategy, design, and elec…
