Additive manufacturing of crystalline materials

DWPI Title: Making organometallic crystalline material involves inducing initial organometallic crystalline seed by positioning direct write source at first position on substrate, where direct write source is configured to produce thermal voxel
Abstract: The present invention relates to additive manufacturing methods, in which crystalline materials can be formed by using a liquid precursor. In particular embodiments, the crystalline material is a perovskite. The methods include the use of a thermal voxel, which can be translated to form any arbitrary pattern of initial crystalline seed structure(s). Then, the seed structure can be incubated to promote crystal growth and/or crystal dissolution, thereby providing a patterned crystalline material.
Use: Method for making organometallic crystalline material.
Advantage: The method enables to make organometallic crystalline material that has optical gain properties and long carrier lifetimes.
Novelty: Making organometallic crystalline material involves inducing initial organometallic crystalline seed by positioning direct write source at first position on substrate, where direct write source is configured to produce thermal voxel and has wavelength of 500-1,000 nanometer. The liquid precursor is in proximity to substrate. The seed is product arising from thermal heating of the liquid precursor by the thermal voxel. The crystal growth or crystal dissolution of the seed is promoted. The organometallic crystalline material that is patterned upon the substrate. The organometallic crystalline material comprises organic moiety.
