Nanomaterials (NMs) have game changing potential in existing and emerging technologies - this is well-illustrated by the recent commercialization of QLED televisions and displays. NM research has even seen ideas and concepts inspired by "science fiction" become reality because of fundamental research that enables exquisite tuning and control of size and surface dependent NM properties. As such, NMs and their assemblies are expected to revolutionize many aspects of modern society including consumer electronics, alternative energy generation as well as storage, healthcare, sensing, optical computing, and even camouflage through the development of light scattering "cloaking" technologies. Unfortunately, many of the exciting prototype advances rely on NMs based upon toxic (e.g., Cd), or comparatively rare (e.g., In) elements. If society is to gain the full benefit of NMs, it is essential that methods be established to predictably prepare, tailor, and manipulate NMs based upon non-toxic, earth abundant elements. Furthermore, achieving these lofty goals is only possible through the preparation, tailoring and testing of real materials - these are the subjects of the present program supported by the NSERC Discovery Program. It will encompass three interconnected themes that exploit and grow our expertise while targeting nanoparticles (or quantum dots) and nanosheets comprised of the earth abundant, non-toxic elements silicon (Si) and germanium (Ge). We will develop new scalable methods for preparing and tailoring the composition, crystal structure, and surface chemistry of these versatile materials. We will also establish structure-property relationships that will provide fundamental practical understanding of Si and Ge NM behavior; these advances will facilitate the design and exploitation of the optical and electronic properties of NMs and their assemblies. In the spirit of discovery, we will also address pressing challenges related to Si nanoparticle/quantum dot applications in displays, sensors, and other optical components; explore revolutionary metamaterial opportunities in which individual (large and small) and assembled Si nanoparticles are predicted to exhibit unique optical responses that do not occur in nature; establish procedures for preparing Ge nanoparticles for solar-cells, field-effect transistors, batteries, photonics, etc.; as well as explore methods to prepare, tailor the properties and manipulate 2D nanosheets of Si and Ge that hold promise in the next generation of electronics and may extend "Moore's Law" and help realize the next generation of advanced computing.

纳米材料（NMS）在现有技术和新兴技术中具有改变游戏的潜力 - 这是QLED电视和显示器的最新商业化所阐明的。 NM研究甚至看到了受“科幻”启发的思想和概念成为现实，因为基本研究能够对大小和表面依赖的NM属性进行精美的调整和控制。因此，NMS及其集会有望彻底改变现代社会的许多方面，包括消费电子产品，替代能源产生以及存储，医疗保健，感应，光学计算，甚至通过开发光散射“掩盖”技术。不幸的是，许多令人兴奋的原型进步都取决于基于有毒（例如CD）或相对罕见（例如，IN）元素的NMS。如果社会要获得NMS的全部利益，那么必须建立基于无毒的地球丰富元素来预测，量身定制和操纵NMS的方法。此外，只有通过准备，定制和测试真实材料才能实现这些崇高的目标 - 这些是NSERC Discovery计划支持的本计划的主题。它将包含三个相互联系的主题，这些主题在靶向纳米颗粒（或量子点）的同时，以及由地球丰富的，无毒的元件硅（SI）和锗（GE）组成的纳米片。我们将开发新的可扩展方法，以准备和调整这些多功能材料的组成，晶体结构和表面化学。我们还将建立结构性关系，将对SI和GE NM行为提供基本的实际理解；这些进步将促进NMS及其组件的光学和电子性能的设计和开发。 本着发现的精神，我们还将解决与Si纳米颗粒/量子点应用有关的挑战，在显示器，传感器和其他光学组件中的挑战；探索革命性的超物质机会，其中预计个体（大小）和组装的Si纳米颗粒会表现出在自然界中不会出现的独特光学响应；建立为太阳能电池，现场效应晶体管，电池，光子学等准备GE纳米颗粒的程序；除了探索准备的方法，定制SI和GE的属性和操纵2D纳米片，在下一代电子产品中有希望，并可能扩展“摩尔定律”并帮助实现下一代高级计算。
