Abstract

Here we present a simple analytical model describing electroabsorption of semiconductor nanocuboids in a wide range of electric field strengths. Using the developed model, we study all the basic electroabsorption effects, including the Stark effect, the Franz-Keldysh effect, and the field-induced broadening of the spectral lines in the nanocrystals spectra. Results of our study can prompt the development of new nanocrystal-based lasers, energy harvesting devices, and electrooptical sensing methods for measuring strong near-fields of plasmonic nanostructures.

Keywords: Electroabsorption, Stark effect, Franz-Keldysh effect
