By 2007, before the iPhone and the iPad were introduced, the US ICT industry already had a larger carbon footprint than the airline industry. Since then, the proliferation of wireless communication devices, of social media (Faceboook, Twitter, Linkedin, etc.) and cloud computing has only exacerbated the annual growth rate of energy consumption attributed to the ICT industry. We now have 2049 data centers worldwide which consume 30 billion Watts, the equivalent of 30 nuclear power stations. On a per capita basis, Canadians rank ahead of Americans in terms of Internet usage and enrollment in social media websites. Our appetite for wireless communication seems insatiable. Unfortunately, of all communication links, wireless is the least efficient. The outlook is just as bleak for computation. Lack of transistor subthreshold slope improvement and lack of appropriate supply voltage scaling during the last 12 years has meant that microprocessors have become power-density limited. While parallel and multicore microprocessor architectures have temporarily alleviated the problem at the expense of increased communication across the chip and stalled clock frequency, only by inventing new transistors with steeper subthreshold slopes, faster transport, and higher current driving capability, which will permit operation from 0.3 to 0.1 V supplies, will the power density trend be curbed or reversed.With a focus on the development of (i) new submillimetre-wave (250-500 GHz) high efficiency digital transmitters for terabit data rate short range wireless communication and of (ii) novel nanoscale metal nanowire and 2-D crystal transistors, this research proposal aims to increase the energy efficiency of data centres and of wireless links by 2-3 orders of magnitude. The research output will consist of the physical implementation of sub-10nm transistors and of short range wireless links operating at close to 0.5 Tb/s. These revolutionary devices and wireless links will help to re-establish Canada's position as a leading player in the ICT field and will lead to radically new technologies, products and companies.

到2007年，在iPhone和iPad推出之前，美国ICT行业的碳足迹已经超过航空业。从那时起，无线通信设备、社交媒体（Facebook、Twitter、Linkedin等）的激增，而云计算只是加剧了ICT行业能源消耗的年增长率。我们现在在全球拥有2049个数据中心，消耗300亿瓦，相当于30个核电站。按人均计算，加拿大人在互联网使用和社交媒体网站注册方面领先于美国人。我们对无线通信的胃口似乎永远无法满足。不幸的是，在所有通信链路中，无线通信是效率最低的。计算的前景同样黯淡。在过去的12年里，由于晶体管亚阈值斜率的改进和电源电压的调整不足，微处理器的功率密度受到了限制。虽然并行和多核微处理器架构以增加芯片上的通信和停滞的时钟频率为代价暂时缓解了这个问题，但只有通过发明具有更陡的亚阈值斜率、更快的传输和更高的电流驱动能力的新晶体管，这将允许在0.3至0.1 V电源下工作，功率密度的趋势是否会受到抑制或逆转。重点是发展（i）新的亚毫米波（250-500 GHz）用于太比特数据速率短程无线通信的高效数字发射机，以及（ii）这项新的纳米金属纳米线和二维晶体管的研究计划旨在提高数据中心和无线连接的能源效率2-3个数量级。研究成果将包括亚10纳米晶体管的物理实现和以接近0.5 Tb/s的速度运行的短程无线链路。这些革命性的设备和无线连接将有助于重新确立加拿大在信息和通信技术领域的领先地位，并将带来全新的技术、产品和公司。
