Semiconductor Nanocrystal Plasmonics
Doped semiconductor nanocrystals with variable free carrier density can support collective oscillations of charge in response to electromagnetic radiation, exhibiting enhanced absorption through localized surface plasmon resonance (LSPR) effect. By electrochemically charging and discharging nanocrystal films, tunable IR-plasmonic electrochromism in energy saving smart window is achieved. [More]
Electrochemical Nanomaterials
The Milliron Group adapts common electrochemical techniques such as cyclic voltammetry, electrochemical impedance spectroscopy and half-cell electrochemical measurements to nanomaterials and extends them with capabilities such as in situ spectroscopic measurements. We utilize our expertise in nanocrystal synthesis to study how changes in size, shape, and doping influence electrochemical properties. [More]
Nanocrystal Assembly and Integration
The unique properties of nanocrystals can yield exciting functionality at larger scales. Beyond what individual nanocrystals can offer, nanocrystal assembly can exbibit emergent collective behavior, opening doors to a broader range of tunability in material properties. By understanding and carefully balancing the inter-nanocrystal attractions and repulsions, ensembles of these nanostructures can be assembled in a controlled fashion. [More]
