We studied ohmic contacts Au-Pd-Ti-Pd-n-AlN and Au-TiB₂-Al-Ti-n-GaN
with contact resistivity ρс = 0.18cm² and 1.6 *10⁻⁴ Ω∙cm² , respectively, and the effect
of microwave treatment on their electrophysical properties. After microwave treatment
for time t up to 1000 s, the contact resistivity dropped by 16% (60%) in the contact to
AlN (GaN). This seems to result from increase of the number of structural defects in the
semiconductor near-contact region caused by relaxation of intrinsic stresses induced by
microwave radiation.
