Influence of structural defects on photoconductivity of zinc diphosphide
Spectral distribution of photoconductivity of initial and gamma-irradiated p-type zinc diphosphide crystals of tetragonal modification has been studied. It is supposed that band hn = 1.65 eV responses to clusters of defects existing in initial crystals. Complex defects appearing during high tempera...

It is supposed that band hn = 1.65 eV responses to clusters of defects existing in initial crystals. Complex defects appearing during high temperature treatment (400oC) form band hn = 1.55-2.14 eV. Irradiation leads to the decrease of dark current and appearing of acceptor type level which can be annealed in the temperature interval 20-100⁰C. |
