Abstract
In a method for producing a I-III-VI compound semiconductor layer, a substrate is provided with a coating which has a metallic precursor layer. The coating is kept, for the duration of a process time, at temperatures of at least 350 degrees C. and the metallic precursor layer, in the presence of a chalcogen at an ambient pressure of between 500 mbar and 1500 mbar, is converted into a compound semiconductor layer. The coating is kept at temperatures for the duration of an activation time which attain at least an activation barrier temperature, whereby as the activation barrier temperature a value of at least 600° C. is selected.
