    摘要： This invention is in the field of physical chemistry and relates to novel hyperuniform and nearly hyperuniform random network materials and methods of making said materials. Methods are described for controlling or altering the band gap of a material, and in particular commercially useful materials such as amorphous silicon. These methods can be exploited in the design of semiconductors, transistors, diodes, solar cells and the like.

    摘要： The invention encompasses compositions and methods for designing or producing three-dimensional articles layer-by-layer, whereby the specific approach to build-up a region of a single layer by fusion, deposition of material, or other path-based process or non-path process that creates track-like geometries requires either differing track or track-like geometry, or track or track-like geometry printing parameters, within a region of a single layer or within adjoining regions of multiple layers, is disclosed. Employing this method, single layer or multilayer parameter-varying fusing and deposition strategies can be generated that reduce article fabrication time and improve article physical properties, in part by targeting a distribution of scan paths that satisfy covering problem overlap and/or dense packing criteria. Additionally, methods and compositions for designing or producing three-dimensional articles by altering the thickness of a material layer deposited during a print relative to the slice thickness or net displacement of a stage or of a material and/or energy-depositing print head, are disclosed. Employing this method can result in the reduction of article fabrication time and/or the improvement of printed article physical properties, where these results advantageous to printing are dependent on the print process, material properties, and feedstock properties employed during the print.
