Interplay between size and impurity position of doped quantum dot

►The interplay between the size and impurity location of a quantum dot has been investigated. ► The quantum dot is doped with a repulsive Gaussian Impurity. ► The spatial arrangement of dot energy levels is affected by the interplay. ► The information entropy profile evinces emergence of resonance-like situations. ► The probability contour delineates the alteration in the spatial extension of the system as a result of the interplay.
