Abstract

The electrical properties and photoluminescence spectra of LEC gallium arsenide crystals after neutron transmutation doping (NTD) have been investigated as function of starting material properties, irradiation dose and thermal to fast neutron fluence ratio. The residual carbon acceptors interact with radiation induced defects (RD) in neutron irradiated GaAs crystals and form nonradiative recombination centers, which are stable up to 700 degrees Celsius.
