D. Pogany et G. Guillot, Random telegraph signal noise instabilities in lattice-mismatched InGaAs InP photodiodes, MICROEL REL, 39(3), 1999, pp. 341-345
Spontaneous and induced instabilities in the character of Random Telegraph
Signal (RTS) noise are studied in photodetector arrays, fabricated on latti
ce-mismatched InGaAs/InP heterostructures. The disappearance and reappearan
ce of the RTS noise as well as abrupt changes in the RTS noise amplitude an
d pulse complexity are investigated as a function of voltage:and temperatur
e. The RTS noise instabilities are explained in terms of structural transfo
rmation of complex multistable crystalline defects. (C) 1999 Elsevier Scien
