Infrared Absorption and Hot Electron Production in Low-Electron-Density Nanospheres: A Look at Real Systems.


Doped semiconductor quantum dots are a new class of plasmonic systems exhibiting infrared resonances. At ultralow concentrations of charge carriers that can be achieved by controlled doping, only few carriers occupy each quantum dot; therefore, a spectrum with well-defined atomic-like peaks is expected. Here we investigate theoretically how surface… (More)
