Abstract
Eigenstates of two different circular quantum dots (quantum ring and quantum disk) are analytically computed by solving time-independent Schrödinger equation in presence of transverse magnetic field. Intraband transition energy is calculated for the lowest three states. Dimensions and magnitude of applied field are tuned to observe the effect on eigenstates and transition energies. Comparative studies for both eigenvalue and transition energies are made between the devices with similar size and under equal applied field. Results show that transition energy decreases with increasing device diameter, and increases with increase of magnetic field. Change in transition energy indicates the possibility of wavelength tuning by magnetic field for optical emitter/detector applications.
