Directed 3D assembly of inorganic semiconducting materials exploiting photochemically triggered building blocks
Abstract
We propose a fundamentally new approach for engineering two- and three-dimensional objects from semiconducting materials. Nano- and micron-sized functional building blocks constructed from inorganic components with defined size, shape, composition, and dopants will be deposited and selectively functionally linked using novel photochemically active all-inorganic bridges to bond the grains, heal interfaces, and dictate material properties. These bridges can be molecular or nanostructured. The process will lead to “modular” (multi)functional materials with performance metrics that can presently only be achieved for crystalline semiconducting solids. We propose prescriptive optical patterning in analogy to 2D photopolymer lithography and stereolithographic 3D printing for direct patterning of optoelectronic components with healed resistive and thermal interfaces. Our team will provide the first demonstration of 3D printing of semiconducting materials. We will exploit the electronic properties of semiconductors and physical properties of granular materials to imbue function on the sub-micron to millimeter scale.
