A Group 3a ink, comprising, as initial components: a polyamine solvent; a Group 3a a material/organic complex; and, a reducing agent; wherein the molar concentration of the reducing agent exceeds the molar concentration of the Group 3a material/organic complex; wherein the Group 3a ink is a stable dispersion and wherein the Group 3a ink is hydrazine and hydrazinium free. Also provided are methods of preparing the Group 3a ink and of using the Group 3a ink to deposit a Group 3a material on a substrate for use in a variety of semiconductor applications, such as metallization of silicon devices in VLSI technology, the growth of semiconducting III-V alloys, thin film transistors (TFTs), light emitting diodes (LEDs); and infrared detectors. |
