Neutron radiation effects in GaAs planar doped barrier diodes

The degradation of GaAs planar doped barrier diodes subject to neutron irradiation is discussed. It is shown that for fluences as high as 10¹⁵ cm^-2, the diode characteristics are very well preserved, which strengthens the rationale for using these devices in place of Schottky diodes in harsh working environments such as nuclear instrumentation and space
