Query: Energy resonance transfer between quantum defects in metal halide
  perovskites   Quantum defects have shown to play an essential role for the non-radiative
recombination in metal halide perovskites (MHPs). Nonetheless, the processes of
charge transfer-assisted by defects are still ambiguous. Herein, we
theoretically study the non-radiative multiphonon processes among different
types of quantum defects in MHPs using Markvart model for the induced
mechanisms of electron-electron and electron-phonon interactions, respectively.
We find that charge carrier can transfer between the neighboring levels of the
same type shallow defects by multiphonon processes, but it will be distinctly
suppressed with the increasing of the defect depth. For the non-radiation
multiphonon transitions between donor- and acceptor-like defects, the processes
are very fast and independence of the defect depth, which provide a possible
explanation for the blinking phenomena of photoluminescence spectra in recent
experiment. We also discuss the temperature dependence of these multiphonon
processes and find that their variational trends depend on the comparison of
Huang-Rhys factor with the emitted phonon number. These theoretical results
fill some gaps of defect-assisted non-radiative processes in the perovskites
materials.
