Abstract
Effects of spatial dependence of recombination centers on the I‐V characteristics of p‐n junctions are calculated. The results obtained show that these effects may explain the experimental deviations from the Shockley p‐n junction theory and from the theory of the carrier generation‐recombination in the space‐charge region. The most important result for applications is the junction in which the lifetime increases in the direction of the carrier diffusion; in this case for diffusion current, at reverse bias, a negative resistance appears.
