Plasmonic nanocavities consisting of metal nanoparticle (NP) arrays support surface lattice resonances (SLR) or lattice plasmon, emerged as an exciting platform for manipulating light-matter interactions at the nanoscale. Their recent prominence can be attributed to a combination of desirable photonic and plasmonic characteristics: high electromagnetic field enhancements extended over large...
The isolation of graphene by the simple Scotch-tape method led to the discovery of many novel two-dimensional (2D) materials. Since then, many new material growth and characterization techniques were proposed and many new phenomena were observed in layered 2D materials. Black phosphorous (BP) and topological insulator(TI) \ce{Bi2Se3} are examples of...
Computational catalysis is a challenging discipline because of the complexity of catalytic particles and the large number of reaction pathways that may occur in a given reaction. This thesis addresses these challenges with two strategies. First, an appropriate molecular model is defined that captures adequate physical and chemical details while...
The anode and cathode are main components in a battery system. In this dissertation, Group IV inter-metallics and LiMn2O4 are studied as anode and cathode materials for Li-ion batteries respectively. Preliminary investigation of a multi-valent cathode material for next generation batteries is also introduced.
Group IV inter-metallics electrochemically alloy with...
