Abstract

We demonstrate a metal-interlayer-semiconductor structure for a non-alloyed source/drain ohmic contact by using a heavily doped ZnO. Therefore, the Fermi-level is effectively alleviated by preventing the metal induced gap state. Finally, we achieved ∼105 x reduction of specific contact resistivity compared to the metal-semiconductor contact. For this reasons, the proposed contact is a promising non-alloyed source/drain ohmic contact for III-V semiconductor based devices.
