摘要:
The invention relates to an ink composition for the in-situ production of chalcogens and/or chalcogenides, characterised in that it comprises at least one chalcogenite compound having a formula selected from a group consisting of SeO 2 , M(SO 3 ) n , M(SeO 3 ) n and M(TeO 3 ) n , wherein 0.5≤n≤2 and M is at least one metal element. In addition, the invention relates to the inks produced using said composition, the production method thereof and the use of same for the in-situ preparation of semiconductor materials.
