Abstract / Description:Significant influence of Mn centers on the radiative and nonradiative
recombinations in Czochralski-grown InP:Mn crystals was observed.
Time-resolved measurements showed that manganese recombination centers
caused very fast, probably subpicosecond, decay of holes and excitons.
This recombination was explained by the capture of holes on an excited
state of the Mn acceptor. The holes trapping coefficient R-Mn
determined on the order of 10(-5) cm(3)/s provided an estimation of the
Mn cross-section for hole capture sigma(p) of the order of 10(-12)
cm(2). Electrical transport measurements showed that hopping
conductivity dominated at low temperatures. From analysis of the
hopping, the wavefunction radius of Mn-bound hole a(f) = 0.74 +/- 0.1
nm was calculated. A model explaining the values of af is presented.
