Abstract

The present invention relates to formulations comprising a) at least two different ZnO cubanes of which at least one ZnO cubane is present in solid form under SATP conditions and at least one ZnO cubane is present in liquid form under SATP conditions, and b) at least one solvent, to processes for producing semiconductive ZnO layers from these formulations, to the use of the formulations for producing electronic components and to the electronic components themselves.
