Abstract
A selenium/Group Ib/Group 3a ink is provided, comprising, as initial components: (a) a selenium/Group Ib/Group 3a system which comprises a combination of, as initial components: a selenium; an organic chalcogenide component; a Group Ib containing substance; optionally, a bidentate thiol component; a Group 3a containing substance; and, (b) a liquid carrier component; wherein the selenium/Group Ib/Group 3a system is stably dispersed in the liquid carrier component. Also provided are methods of preparing the selenium/Group Ib/Group 3a ink and for using the selenium/Group Ib/Group 3a ink to deposit a selenium/Group Ib/Group 3a material on a substrate for use in the manufacture of a variety of chalcogenide containing semiconductor materials, such as, thin film transistors (TFTs), light emitting diodes (LEDs); and photoresponsive devices (e.g., electrophotography (e.g., laser printers and copiers), rectifiers, photographic exposure meters and photovoltaic cells) and chalcogenide containing phase change memory materials.
