“Many Faces of Carbon”
Abstract: Carbon is one of the most fascinating elements in the periodic table. It not only forms the basis of all life on the Earth but also it is important to technology. The unique properties of carbon emerge from its ability to form diverse spn (1 < n < 3) bonds. Until 1960’s graphite with sp2 and diamond with sp3 bonding were the most common forms of carbon known. The discovery of one-dimensional (1D) chain-like polymer called “carbyne” in 1960 and later zero-dimensional (0D) carbon fullerenes, 1D carbon nanotube, and two-dimensional (2D) graphene, all with novel properties characteristic of their reduced dimensionality and size, has ushered a new era in carbon science. In recent years many new meta-stable forms of carbon exhibiting a mixture sp1, sp2 and/or sp3 bonding pattern have also emerged. In this talk I will focus on the carbon allotropes that have been studied in our group. These include functionalized C60 fullerenes for hydrogen storage, semi-hydrogenated graphene for metal-free ferromagnet, metal-organic complexes with large electron affinity, 3D metallic carbon made of hybridized sp2 and sp3 bonded atoms, a Cairo-tilling inspired quasi-2D penta-graphene made of only carbon pentagons, and its thermal conductivity. All calculations have been carried out using gradient corrected density functional theory. Thermodynamic stability of the above carbon allotropes is confirmed by total energy calculations as well as quantum molecular dynamics. Potential applications of some of these carbon allotropes will be discussed.
Bio: Prof. Puru Jena is a distinguished professor of physics at Virginia Commonwealth
University. He received his Ph. D. in Physics from the University of California at
Riverside in 1970. After postdoctoral and several visiting appointments, he joined
Michigan Technological University, Houghton as an Associate Professor of
Physics in 1978. Then he became a full professor at Virginia Commonwealth
University, Richmond in 1980. He has been a Program Director at the Materials
Science Division of the National Science Foundation, and a year (2007-08) as a
Jefferson Science Fellow and Senior Science Advisor at the US Department of State.
Prof. Jena’s research covers a broad area of research in condensed matter Physics, and materials Science which include structure and properties of metals, semiconductors, superconductors, alloys, liquid metals, point and complex defects, surfaces, thin films, atomic clusters, and cluster assembled materials. His current research is focused on three major areas: Structure and properties of nano-clusters and cluster assembled materials (0 D), nanotubes and nanowires (1D) and mono- and multi layered materials (2D) with emphasis on energy storage; electronic, magnetic, and optical properties. Prof. Jena is the author of nearly 525 papers including 12 edited books. More information about Prof. Jena is available at
