This postdoctoral research opportunity at the Naval Research Laboratory (NRL) focuses on ultrafast studies of charge transfer plasmonics. The project aims to control the resonance wavelength in plasmonic nanostructures by connecting two plasmonic nanoparticles with a thin metallic bridge, forming a metamolecule. By precisely controlling interparticle charge transfer through the nanojunction's size, shape, and material, researchers can tailor the absorption peak wavelength to arbitrary values, enabling disruptive optical technologies.
The research involves non-thermal welding of plasmonic nanoparticles into discrete morphologies interconnected by metallic nanojunctions using molecular assembly and femtosecond laser pulses. Understanding and controlling the formation and morphology of these nanojunctions during the femtosecond-scale welding process is critical for developing engineered materials with tunable optical properties.
Applicants should have demonstrated expertise in ultrafast spectroscopies and a strong background in physics, chemistry, materials science, or engineering related to plasmonics and nanostructures.
