项目摘要

Electronic equipment accounts for a significant fraction of our rapidly increasing global demand for energy and it is projected to consume 30% of our energy budget in 10 years. Improving the energy efficiency in electronic devices such as the transistor at the computing core of data centers, or the light-emitting diode that will become pervasive in lighting applications, can have a remarkable influence on a country's future economy and environmental impact.******Heat transport has profound effects on the energy efficiency, performance and reliability of electronic devices. Particularly at the nanoscale, heat flow is greatly affected by low-dimensionality, device geometry and the presence of interfaces across materials with dissimilar phonon spectra. As device size is reduced or more functionality is added, the quality and number of interfaces that pose as barriers to heat flow have greater impact, and understanding their role can lead to ways to engineer energy-efficient devices. On a fundamental level, knowledge of how heat flow affects electronic transport phenomena can drive the discovery of new functionality. The proposed research aims to answer the following questions: how is heat transported in novel materials that may be used in future electronic devices? How can interfaces be tailored to improve cooling efficiency? How can one probe heat transport at the nanoscale? Answering these questions can in the long term shape the functionality and energy use of the evolving electronics landscape.******Versatile optical pump-probe techniques have emerged to investigate heat transport in materials, interfaces and composites. In the short term we will adopt and extend these techniques to make them sensitive to heat transport over a large range of heat transport length scales, in order to span the diffusive to the quasi-ballistic limits. Additionally, electrical thermometry will allow us to probe devices locally. These tools will be applied to the study of heat flow in: (i) emerging 2-dimensional electronic materials, (ii) nanoscale composites with high thermal anisotropy, (iii) magnetic junctions used in magnetic field sensors and magnetic random access memories.******The impact of this work will benefit Canada's economy in the short term through the training of highly qualified personnel and raising the profile of the country's university research work. Furthermore, research on thermal anisotropy in composites has immediate applications in the data storage industry, and can contribute directly to progress in hard disk drive products. In the long run this research program will improve the performance, energy efficiency and environmental impact of the world's rapidly growing electronic, computing and telecommunications infrastructure.
电子设备占我们快速增长的全球能源需求的很大一部分,预计在10年内将消耗我们能源预算的30%。提高电子设备的能源效率,如数据中心计算核心的晶体管,或将在照明应用中普及的发光二极管,可以对一个国家未来的经济和环境影响产生显着影响。热传输对电子设备的能效、性能和可靠性有着深远的影响。特别是在纳米尺度下,低维、器件几何形状和具有不同声子谱的材料之间的界面的存在极大地影响了热流。 随着设备尺寸的减小或功能的增加,作为热流屏障的接口的质量和数量会产生更大的影响,了解它们的作用可以找到设计节能设备的方法。在基础层面上,了解热流如何影响电子输运现象可以推动新功能的发现。这项研究旨在回答以下问题:在未来电子设备中可能使用的新型材料中,热量是如何传输的?如何定制接口以提高冷却效率?如何探测纳米尺度的热传输?从长远来看,解决这些问题可以塑造不断发展的电子领域的功能和能源使用。多功能的光学泵浦探测技术已经出现,用于研究材料、界面和复合材料中的热传输。在短期内,我们将采用并扩展这些技术,使它们对大范围的热传输长度尺度上的热传输敏感,以跨越扩散到准弹道极限。此外,电子温度测量将允许我们在本地探测设备。这些工具将应用于热流的研究:(i)新兴的二维电子材料,(ii)具有高热各向异性的纳米级复合材料,(iii)用于磁场传感器和磁性随机存取存储器的磁性结。这项工作的影响将通过培训高素质的人才和提高该国大学研究工作的形象,在短期内有利于加拿大的经济。此外,对复合材料中的热各向异性的研究在数据存储工业中具有直接的应用,并且可以直接有助于硬盘驱动器产品的进步。从长远来看,这项研究计划将提高世界上快速增长的电子,计算和电信基础设施的性能,能源效率和环境影响。
