The cyclotron resonance of impurity magnetopolarons in two-dimensional quantum dots for all coupling strengths

► This paper studied a bound magnetopolaron in a 2D symmetric semiconductor QD. ► An all-coupling variational approach is employed to obtain the GS and ES energies. ► An analysis of how the cyclotron mass depends on the confinement length is presented. ► An analysis of how the cyclotron mass depends on impurity strength is presented.
