Multiphonon recombination of carriers at frozen-photoconductivity centers in PbTe films
Baklanov K. A. , Krylov I. P.
A method involving a second illumination has established the existence of a metastable state of photoactive centers with a typical lifetime > 106 s. The temperature dependence of the recombination to the ground state indicates a pronounced local lattice deformation accompanying a change in the charge state of a defect.
