The temporal evolution of the ambipolar diffusivity of optically excited electron–hole pairs is investigated for a strained quantum well structure by temporally and spatially resolved pump and probe experiments. Dependent on the excitation conditions the diffusivity transients reflect the cooling and ...
The effect of the electron–hole correlations on the effective mass electronic states of donor–acceptor (DA) pairs in polar semiconductors is investigated. Variational calculations are carried out and compared with previous theoretical work in the case of GaP and ZnSe. Analytic expressions for the ...
The formation of electron–hole-trapping centers in phosphates was observed during photon irradiation, with energies surpassing the band gap, leading to the creation of free electron–hole pairs. In the research conducted by authors [5], thermoluminescence (TL) was studied in 𝑌𝑃𝑂4YPO4 dop...
