Measurements of electrical conductivity and Rutherford backscattering are used to study the accumulation of defects in GaAs that has been subjected to pulsed (τp = 1.3 × 10(-2) s and an off-duty factor of 100) and continuous irradiation with 32S, 12C, and 4He ions at room temperature at the ion energies E = 100-150 keV, doses Φ = 1 × 109-6 × 10-6 cm(-2), and current densities j = 1 × 10(-9)-3 × 10(-6) A cm(-2). It is shown that the defect-accumulation rate during the pulsed implantation is much lower than it is during the continuous implantation.
