The Role of the Axes of the Three Metal Nano-ellipsoids of Size Constant in the Energy Absorption Rate Change in the Hybrid System

Abstract This work discusses the three-dimensional hybrid system of three metal nano-ellipsoids and semiconductor quantum dot to obtain the energy absorption rate caused by the direct and indirect contribution of the interaction between the semiconductor quantum dot and the three metal nano-ellipsoids. We investigate the interaction between excitons and surface plasmons by applying three electromagnetic fields in the three-dimensional directions. We calculate the polarization of the three metal nano-ellipsoids to evaluate the energy absorption rate for all three metal nano-ellipsoids. The energy absorption rate of the semiconductor quantum dot via three electromagnetic fields in the three dimensions is studied. We demonstrated that although the size of the three metal nano-ellipsoids is equal, the axes of the three metal nano-ellipsoids can play a distinct role in influencing energy absorption. We also demonstrated the varying distances between the three metal nano-ellipsoids affect the energy absorption rate. We found the dielectric constant of the surrounding material and semiconductor quantum dot influence the energy absorption rate of the semiconductor quantum dot.
