NSAC/NCN Seminar Series 2012 Topic: Field-matter interactions can be exploited for various pursuits in nanotechnology. Abstract: Field-matter interactions can be exploited for various pursuits in nanotechnology.I shall present highlights of my research activity which spans over past 10 years. Fields (electric field/laser) have been observed to induce material modifications. Photochemical transformations for carbon materials at reduced dimensionality such as graphene (2D) and carbon nanotubes (1D) will also be presented. Excited state electron transfer has been employed to achieve white light in graphene- ZnO nanocomposite systems and enhanced photocatalysis in graphene-TiO2 nanocomposite systems. Lasing action in semiconductor nanostructures is yet another area which is relevant for field-matter interactions. Speaker: Dr. Prashant Kumar, got his Master's degree in Physics in 2003 from Jawaharlal Nehru University, New Delhi and Ph.D in Physics in 2009 from University of Hyderabad.Currently he is a visiting scholar at Birck Nanotechnology Centre and working with Prof. Fisher. Date/time: Thursday, March 23, 2012 3:30 PM- 4:30 PM at Birck 1001 Refreshment will served. -----------------------
