Title of Talk:

*/"Plasmonics and Magneto-Plasmonics in Thin Films and Nanostructures"/*

*Abstract:*The work presented here concerns the optical and 
magneto-optical responses of thin films (metallic, conducting oxide, and 
metal-to-insulator phase transition thin films) and metallic 
nanoparticles, under the excitation of surface plasmon polaritons (SPPs) 
and localized surface plasmon resonance (LSPR). The underlying aim of 
this thesis is to build the current understanding of SPP/LSPR excitation 
in various nano- materials, and thus provide exciting alternatives in 
plasmonic based applications.  In this thesis, we present our research 
work on SPPs and LSPR studies in different kinds of thin films and 
nanoparticles. We present theoretical and experimental studies on the 
observed strong enhancement of the magneto-optical Faraday rotation in 
all-metal core-shell Fe-Ag/Co-Ag nanoparticles, attributed to strong 
LSPR excitation in the noble metal shells. We also report observation of 
optically excited SPPs and bulk plasmons in ruthenium oxide (RuO_2 ) 
thin films, offering an exciting alternative to conventional metals for 
metamaterials and plasmonic applications, due to their low optical 
losses in the visible and near-infrared ranges. Finally, we report on 
the first observation of optically excited tunable SPPs in vanadium 
dioxide (VO_2 ) thin films during its thermally induced 
metal-to-insulator phase transition.

*Bio:*Lei Wang was born in Lishu, Jilin Province, China in 1984. She 
attended the University of Science and Technology of China and was 
awarded her Bachelor's degree in 2008.  After graduation, she continued 
her studies in physics at the College of William and Mary, being awarded 
her Master's degree in 2010.  She is currently pursuing her PhD degree 
in Physics at the College of William and Mary where she is expecting her 
degree to be awarded in May 2015.

Open to the public.
