Optoelectronic component with electrically-conductive adhesive layer including titanium oxide and method for producing the optoelectronic component

A method for producing an optoelectronic component, including the method steps:

• A) providing a semiconductor layer sequence with an active layer configured to emit electromagnetic radiation during operation of the component;
• B) applying a current expansion layer on to a radiation exit surface of the semiconductor layer sequence;
• C) applying an adhesive layeron to the current expansion layer;
• D) applying a contact structureon to the current expansion layer;
• wherein the method step C) includes the following method steps:
• C1) vaporization of a titanium oxide, wherein the oxygen in the titanium oxide has the oxidation state W0 with W0=−2 and the titanium has the oxidation state WT with 0<WT<+4, or
• C1′) vaporization of titanium while supplying oxygen;
• C3) depositing a titanium oxide for forming the adhesive layer (4), wherein the oxygen in the titanium oxide has the oxidation state W0 with W0=−2 and the titanium has the oxidation state WT with 0<WT<+4,
• wherein the adhesive layer includes a titanium suboxide with the formula Ti3O or Ti6O or TinO2n−1 with n=3-10.
