Yg. Zhao et al., EFFECT OF PERSISTENT PHOTOCONDUCTIVITY ON PHOTOCONDUCTIVITY SPECTRA IN GAXIN1-XP INP-FE (X-LESS-THAN-0.18)/, Solid state communications, 96(11), 1995, pp. 843-846
We have observed and analyzed the effect of persistent photoconductivi
ty on the photoconductivity spectra in GaxIn1-xP/InP:Fe (x < 0.18), an
d have suggested various possible ways to reduce the effect. Using the
assumption of a macroscopic potential barrier between the substrate a
nd the film we have explained the experimental results.
