Low‐Resistivity Ti/Al/TiN/Au Ohmic Contacts to Ga‐ and N‐Face n‐GaN for Vertical Power Devices Phys. Status Solidi A (IF 2.0) Pub Date : 2024-04-18 Oskar Sadowski, Maciej Kamiński, Andrzej Taube, Jarosław Tarenko, Marek Guziewicz, Marek Wzorek, Justyna Maleszyk, Iwona Jóźwik, Anna Szerling, Paweł Prystawko, Michał Boćkowski, Izabella Grzegory
Low‐resistivity Ohmic contacts to Gallium‐face (G‐aface) and/or Nitrogen‐face (‐Nface) n‐GaN are undoubtedly needed for high‐quality vertical power devices. Contrary to Ga‐face n‐GaN, for which the Ohmic contact formation is a well‐established process, the formation of low‐resistivity Ohmic contacts to N‐face n‐GaN is much more difficult due to the different surface properties. Despite many efforts
