Advanced technologies rely heavily on the engineering of materials with properties and capabilities not found in nature. Examples include thin films, nanostructured materials, and advanced composites with properties superior to those of their constituents. This revolution in materials synthesis, however, would be impossible without the availability of methods of characterization and analysis that can keep pace with the reduced tolerance for defects and the need to understand structure and composition on an atomic scale. In turn, the results of detailed materials analysis can be used to provide feedback to the fabrication and processing stage, thereby further improving materials and device properties and tailoring them for specific applications, including photonics. One of the key distinguishing features of the proposed research program is the intimate link between fabrication and characterization. The long-term objective of this program of research is to design, fabricate and comprehensively characterize complex thin film structures, including -silicon--based systems for photonics applications. The principal aim is to address, in a rigorous research approach and using state--of--the--art research infrastructure, issues with a high potential impact on the science of advanced materials and the manufacturing process. The McMaster Intense Positron Beam Facility , expected to be operational by mid--2019, will give us the capacity to depth-profile open-volume defects in thin film structures, at the level of single missing or misplaced atoms, and under dynamic conditions. It will be unique in Canada and one of only a few operating worldwide. In the next 5 years, we will pursue the following short term objectives: 1) gain a better understanding of features at the atomic level that determine the optical, electronic, and mechanical properties of silicon-based thin film structures, 2) design and optimize materials (such as SiCxNy:H), structures and devices for applications in harsh environments, 3) study in detail the plasma processes leading to desired materials properties, and 4) provide a strong and direct link between advanced materials science and industry-relevant fabrication technology. The HQP participating in the various projects will acquire hands--on experience in areas of high scientific and economic relevance. For example, silicon-based photonic elements are highly desirable components of optical communication systems, solid state lighting, and all-silicon solar cells. Thus, silicon photonics is an internationally hotly pursued field, with potentially massive economic benefits. The HQP will work in some of the best materials research facilities in Canada, in multi--user, multi--disciplinary environments. The collaborations with our international partners provide the HQP with the opportunity to work at renowned laboratories abroad, which ensures a vibrant and stimulating research environment and fosters greater global awareness.

先进的技术在很大程度上依赖于具有自然界中特性和能力的材料的工程。例子包括薄膜，纳米结构材料和高级复合材料，其特性优于其成分。然而，如果没有表征和分析方法的可用性，材料合成的这一革命将是不可能的，这可以使对缺陷的容忍度降低以及在原子规模上理解结构和组成的需求。反过来，详细的材料分析的结果可用于提供对制造和加工阶段的反馈，从而进一步改善材料和设备特性，并为包括光子学在内的特定应用调整它们。拟议的研究计划的主要区别特征之一是制造与表征之间的紧密联系。 该研究计划的长期目标是设计，制造和全面地表征复杂的薄膜结构，包括基于-silicon的光子学应用系统。主要目的是在严格的研究方法中解决，并使用先进的研究基础设施的状态，对高级材料科学和制造过程产生高潜在影响的问题。预计到2019年中期将在薄膜结构，单个缺失或放错的原子和动态条件下，麦克马斯特的激发正电子光束设施预计将在薄膜结构，单个缺失或放错的原子的水平下，将使我们能够有能力在薄膜结构中具有深度的开放量缺陷。它在加拿大和全球仅有的少数几个在加拿大中都是独一无二的。 In the next 5 years, we will pursue the following short term objectives: 1) gain a better understanding of features at the atomic level that determine the optical, electronic, and mechanical properties of silicon-based thin film structures, 2) design and optimize materials (such as SiCxNy:H), structures and devices for applications in harsh environments, 3) study in detail the plasma processes leading to desired materials properties, and 4) provide a strong and direct link between advanced materials科学和行业与工业相关的制造技术。 参与各种项目的HQP将获得高科学和经济相关领域的经验。例如，基于硅的光子元件是光学通信系统，固态照明和全硅硅太阳能电池的高度理想的组成部分。因此，硅光子学是一个国际上热门的领域，具有巨大的经济利益。 HQP将在加拿大的一些最佳材料研究设施中工作，在多学科的多学科环境中。与我们的国际合作伙伴的合作为HQP提供了在国外著名的实验室工作的机会，这确保了充满活力和刺激的研究环境，并提高了更大的全球意识。
