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.
