I. Thurzo et al., CURRENT-VOLTAGE CHARACTERISTICS AND CHARGE DLTS SPECTRA OF PROTON-BOMBARDED SCHOTTKY DIODES ON SEMIINSULATING GAAS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 83(1-2), 1993, pp. 145-152
Changes in the current-voltage characteristics and charge DLTS spectra
of Schottky diodes on semi-insulating GaAs after irradiation by proto
ns at different energies and doses are presented and discussed. Apart
from a progressive degradation of the Schottky barriers with enhanced
proton energy and dose, there is a threshold, positioned between 10(14
) and 10(15) protons/cm2, for observing trap-limited transients.
