This project focuses on the development of precursors for inkjet printing of semiconductors, specifically stibnite (Sb2S3). For inkjet printable semiconductors one issue is the maintenance of extrusion area of the printer, where the nozzle could continuously get clogged due to growth and clumping. To combat this, the developed precursors would be extruded and deposit the semiconductor onto a glass surface. Structural and electronic properties of stibnite were analyzed using x-ray photoelectron spectroscopy and x-ray diffraction. Surface tension and viscosity measurements were done to match the thermofluidic requirements the precursors would need to for an existing inkjet printer.
