Degradation of voltage-current characteristics of gallium phosphide diodes due to radiation-induced defects - Dubovyi, V.K.; Kanevsky, S.O.; Litovchenko, P.G.; Opilat, V.Ya.; Tartachnik, V.P. (Functional Materials, 2005)
The GaP diode radiation-induced degradation has been established to be caused mainlу bу the reduction of the current carrier lifetime resulting from introduction of non-radiative deep levels of the radiation-induced defects. A thin structure has been revealed in the voltage-current characteristics (VAC) at temperatures lower than 90 К. The existence of oscillations are associated with the capturing of non-equilibrium current carriers bу traps followed bу thermal destruction thereof. A characteristic VAC feature of the neutron-irradiated samples is the occurrence of an N-like of negative differential resistance. This deviation from the VAC monotonicitу is explained bу thermallу-induced transformations of the disorder areas.
