Abstract
A p-type ohmic metal electrode for use with a group II-VI semiconductor device. The p-type ohmic metal electrode is made of a group II-IV p-type semiconductor layer having a group II element other than zinc dispersed in that layer disposed on the group II-IV semiconductor device, and a metal electrode layer disposed on the group II-IV semiconductor layer including the group II element other than zinc. Also disclosed is a group II-IV semiconductor device including a p-type group II-IV semiconductor containing zinc and selenium and the above ohmic metal electrode disposed on the group II-IV semiconductor device. Additionally, a group II-IV semiconductor device including a p-type group II-IV semiconductor containing zinc and selenium, a layer of a group II element other than zinc disposed on the group II-IV semiconductor device, and a metal electrode layer disposed on the layer of the group II element other than zinc is disclosed.
