| Abstract: | We report a new photomemory effect in semi-insulating bulk GaAs. Persistent illumination with 1.15 eV photons induces a photosensitivity state in GaAs, which is characterized by a slow decay of the photoconductivity, after the light is switched-off. The most relevant phenomenological aspects of this effect are summarized in this communication. |
