Abstract

This paper reports a generalized direct optical printing technique to obtain functional metal chalcogenides via digital light processing. Photocurable chalcogenidometallate inks were developed to create 2D patterns or micrometer-thick 2.5D architectures. The process is applicable to various functional metal chalcogenides. A micro-scale thermoelectric generator was fabricated and evaluated, demonstrating the technique's potential for cost-effective architecturing of functional inorganic materials.
