Effect of microwave treatment on current flow mechanism in ohmic contacts to GaN
The temperature dependence of contact resistivity ρс of Ti-Al-TiB₂-Au ohmic
 contacts to n-GaN and effect of microwave treatment on ρс are investigated. The obtained
 dependences are described using a model of current flow via metal shunts associated
 with dislocations, the c...

| description | The temperature dependence of contact resistivity ρс of Ti-Al-TiB₂-Au ohmic
contacts to n-GaN and effect of microwave treatment on ρс are investigated. The obtained
dependences are described using a model of current flow via metal shunts associated
with dislocations, the current being limited by diffusion supply of electrons. It is shown
that microwave treatment increases the dislocation density in the near-contact region of
contact structure and reduces the relative spread of resistivity values of contacts formed
on the wafer.
