The Rôle of Defects in Photographic Latent Image Formation


We report a density functional theory study of the structure and energies of point defects in silver chloride. The localisation of photoelectrons and corresponding holes at these defects has been studied, along with the corresponding relaxation of the lattice. We have applied state-of-the-art periodic and QM/MM embedding methods, to provide new insights into the long-standing problem of the fundamental processes controlling latent image formation.
