Özet

This paper investigates the electronic and optical properties of isotropic and anisotropic two-dimensional quantum dots modelled using the Deng-Fan oscillator potential subjected to hydrostatic pressure. Since the Hamiltonian of the two-dimensional quantum dot can be separated into independent variables, the energy spectrum for each direction was obtained by solving the one-dimensional time independent Schrödinger equation using the diagonalization method. The density matrix formalism was then employed to calculate the optical absorption coefficients related to intraband transitions. The results demonstrate that hydrostatic pressure, the geometry of the dot material, and anisotropy can act as effective control parameters for tuning the electronic and optical properties of QDs.
