Development of Amorphous Metal Thin Films for Thermal Inkjet Printing
With their lack of grains and grain boundaries, amorphous metals are known to possess advantageous mechanical properties and enhanced chemical stability relative to crystalline metals. This makes amorphous metals optimal candidates for micro-electromechanical system applications, such as thermal inkjet printing. Commonly, however, amorphous metal thin films (AMTFs) exhibit poor high-temperature stability because of their metastable nature.

The goal of this work is to synthesize, characterize, and evaluate new Ta-based AMTFs that are suitable for the TIJ cavitation plate and resistor applications. Currently, three AMTF alloys, composed of TaWSi, TaHfSi, and TaNiSi, have been developed and show promising material properties with thermal stabilities > 600 °C. Additionally, these materials will be extended to other thin film applications, such as electrodes.
