Abstract:
In CdSe nanoplatelet, interband transitions in the presence of an axial electric field are considered. It is shown that at certain nanoplatelet thicknesses, the combined effect of polarization and confining potentials forms an effective parabolic potential in the axial direction. As a consequence, the influence of the electric field in this direction can be described within the framework of the one-dimensional mixed oscillator model. Analytical formulas for the energy spectrum and wave function are obtained, threshold frequencies are determined for different monolayer thicknesses.
