Intensity-dependent relaxation of photoconductivity in nanocrystalline titania thin films
We have discovered that the initial rate of the post-illumination decay of photoconductivity in nanocrystalline Ti O2 depends on the intensity of the illumination. The phenomenon is described by hole detrapping processes affected by electrostatic interactions between the trapped holes, and screening...
