Abstract
The effect of vacuum annealing on the electrical properties of undoped lead sulfide epilayers on barium fluoride substrates was characterize d by Hall effect measurements. The through-thickness variation in the concentration of nonstoichiometric defects is attributed to sulfur eva poration from the surface layer. In p-type layers, type conversion in the near-surface region results in the formation of a p-n junction, wi th parameters controlled by annealing temperature and time.
