Abstract
Characteristic wavelength carrying the signature of virus is analytically determined through its match with the radiating wavelength comes out from computation of intersubband transition energies of different circular quantum dots, namely quantum ring and quantum disk. Time-independent Schrödinger equation is solved subject to the applied electric field along the axis, and first and second order Bessel functions are considered for computation of energy subbands. Non-monotonic spacing of quantized energy states have been observed by changing different dimensions of the quantum dots. Three lowest confinement states along with subband energies are plotted with different structural parameters, and also with external field. Comparative study reveals that better tuning of intersubband transition energy can be achieved in quantum ring than quantum disk having similar structural parameters; which reveals the fact that characteristic wavelength from quantum ring can track wider rage of virus signature. Tailoring of wavelength can be revealed by notifying the blueshift/redshift in absorption spectra in the choice of frequency region.
