Donor dynamics of reverse type I core/shell nanostructure embedded in inorganic and organic polymer matrices
Source abstract
Abstract
The role of surface ligand in tuning the carrier dynamics of reverse type I Al0.3Ga0.7As/ GaAs Core/Shell Nanostructure (CSN) has been investigated by considering two different ligand matrices: (i) inorganic 2D SiO2 and (ii) organic 2D conjugated polymer (2D-CP) with barrier potentials of 3.9 eV and 0.784 eV, respectively. The effective mass approximation combined with the variation technique is used to calculate the numerical results. The impact of ligand on the binding energy (BE) and diamagnetic susceptibility (χdia) of donor is examined for various donor locations (R) at varied core (Rc) and shell (Rs) radii. The spatial extent of carriers (red2) manifests the tunneling ability of electrons in the CSNs. The system exhibits diverse behavior and increased stability in the presence of organic 2D-CP and inorganic 2D SiO2 matrix. The present work will update the significance of ligand passivated reverse type I CSN for effective quantum tunneling devices.
