项目摘要

Atomically thin materials provide a wide range of fundamental semiconductor device building blocks with unique electronic and optical properties which do not exist in the bulk. Remarkably, the atomic sheets can be stacked together without restriction to form heterostructures with unprecedented properties and capabilities. To date, heterostructure devices consisting of only a handful of individual atomic layers have led to extraordinary breakthroughs in photonics, electronics, and quantum materials. A tantalizing dream is to go beyond these few-layer systems and construct designer materials comprised of tens, hundreds, or even thousands of atomic layers, each precisely chosen and placed. Unfortunately, state-of-the-art layer-by-layer fabrication of such structures is tedious, low-yield, and not reproducible at the quantum level.Inspired by nature, 2D-Gecko aims to revolutionize the layer-by-layer-fabrication of heterostructures to realize highly reproducible materials and devices of limitless complexity. We will pioneer "smart" pick-and-place assembly of individual atomic sheets using microfibril arrays, similar to a gecko, to achieve reversible adhesion - switchable via mechanical actuation. We will incorporate this technology into a fully autonomous pilot line, combining robotic control of all assembly steps with efficient computer-vision, machine intelligence algorithms, and in-situ metrology techniques for quality control. The pilot line will be exploited to fabricate highly tunable quantum materials based on stacking layers with a relative twist (so-called moiré heterostructures) in a reproducible and deterministic fashion. Ultimately, we aim to realize scalable moiré materials, with reproducibility at the quantum level, such that programmable three-dimensional moiré solids can be realized.

原子薄材料提供了各种具有独特电子和光学特性的基本半导体器件构建块，这些特性在本体中是不存在的。值得注意的是，原子片可以不受限制地堆叠在一起，形成具有前所未有的特性和功能的异质结构。仅由少数单个原子层组成的异质结构器件已经在光子学、电子学和量子材料领域取得了非凡的突破，一个诱人的梦想是超越这些几层系统并构建由数十、数百甚至数千组成的设计材料。的不幸的是，这种结构的最先进的逐层制造是乏味的、低产量的，并且无法在量子水平上重现。受到大自然的启发，2D-Gecko 的目标是。彻底改变异质结构的逐层制造，以实现高度可重复的材料和无限复杂性的设备，我们将率先使用单个原子片的“智能”拾取和放置组装。类似于壁虎的微纤维阵列，以实现可逆粘附 - 可通过机械驱动进行切换，我们将把这项技术纳入完全自主的试验线，将所有装配步骤的机器人控制与高效的计算机视觉、机器智能算法和内部结合起来。用于质量控制的原位计量技术将用于以可重复和确定性的方式制造基于具有相对扭曲的堆叠层（所谓的莫尔异质结构）的高度可调的量子材料。最终，我们的目标是实现可扩展的莫尔材料，并在量子水平上具有可重复性，从而可以实现可编程的三维莫尔固体。
