Annotation | The influence of ionizing radiation from 226Ra source on the electrical and photoluminescent properties of porous silicon nanostructures was investigated. After the radiation exposure, AC resistance of experimental samples decreased and luminescence band was changed. Temperature dependencies of electrical conductivity and depolarization current were studied in 80-325 K temperature range. Effect of radiation on the energy distribution of localized electronic states in porous silicon based structures is analyzed. Obtained results expand the application prospective of porous silicon for radiation sensing. |
