Additive Manufacturing of Two-Dimensional nanosheet networks for miniaturized structures

Robocasting或直接油墨写入是一种可扩展的增材制造技术，其带来了以三维（3D）几何形状制造小型化设备的可能性。三维上的小型化对于未来的片上技术是非常有吸引力的，其中需要在小尺寸上优化效率。这是一个新的挑战，因为器件小型化主要是为了实现平面几何形状。这个博士项目的目标是配制高度浓缩的水基2D原子薄材料油墨，这些油墨是可打印的，并制造新颖的小型化架构。油墨由三元合金材料的原子级薄片组成，所述三元合金材料从本体剥离或通过在溶液中直接合成获得。通过调整配制油墨的流变性，将实现剪切稀化行为，从而允许印刷性并确保印刷结构的机械完整性

Robocasting or Direct Ink Writing, is a scalable additive manufacturing technique that brings the possibility of making minaturized devices in three-dimensional (3D) geometry. Miniaturization over three-dimensional is very attractive for future on-chip technologies where efficiencies need to be optimized over small footprints. This is a new challenge, as device miniaturization is mainly developed to achieve planar-geometries. The objective if this PhD project is to formulate highly concentrated, water-based 2D atomically thin material inks which are printable and to fabricate novel miniaturized architectures. The inks are composed by atomically thin sheets of ternary alloy materials either exfoliated from bulk or obtained via direct synthesis in solution. By tailoring the rheology of the formulated inks, a shear thinning behaviour will be achieved allowing printability and assuring mechanical integrity of our printed structures
