Effect of magnetic field, size and donor position on the absorption coefficients related a donor within the core/shell/shell quantum dot

In this study, linear, nonlinear and total optical absorption coefficients related a single shallow donor atom confined in semiconductor core/shell/shell quantum dot heterostructure are researched detail within the compact density matrix formalism approximation. For purpose, firstly, energies wavefunctions computed by diagonalization method effective mass approach. Moreover, effects of size modulation, position magnetic field analyzed. The numerical results indicate that linear parts with intersubband $$1s\rightarrow 1p$$ $$1p\rightarrow 1d$$ transitions undergo significant changes.
