摘要:

了解纳米结构中的能量耗散和传输对于设计节能电路和能量转换系统具有重要意义。这也是一个丰富的领域,在电子,晶格(声子)和光学(光子)相互作用的交叉点的基本发现。本文综述了纳米固态结构中能量耗散和输运的研究进展。首先,调查了从纳米级晶体管(~10^-8 W)到大型数据中心(~ 10 ^9 W)的电力使用情况。然后,重点是在纳米电路,硅晶体管,碳纳米结构和半导体纳米线的能量耗散。稳态和瞬态热传输的概念也审查的上下文中的纳米器件与亚纳秒开关时间。最后,关于能量传输的最新方向进行了审查,包括纳米结构的导电性和导热性,热整流,无处不在的材料界面的作用。

英文摘要:

Understanding energy dissipation and transport in nanoscale structures is of great importance for the design of energy-efficient circuits and energy-conversion systems. This is also a rich domain for fundamental discoveries at the intersection of electron, lattice (phonon), and optical (photon) interactions. This review presents recent progress in understanding and manipulation of energy dissipation and transport in nanoscale solid-state structures. First, the landscape of power usage from nanoscale transistors (~10^-8 W) to massive data centers (~10^9 W) is surveyed. Then, focus is given to energy dissipation in nanoscale circuits, silicon transistors, carbon nanostructures, and semiconductor nanowires. Concepts of steady-state and transient thermal transport are also reviewed in the context of nanoscale devices with sub-nanosecond switching times. Finally, recent directions regarding energy transport are reviewed, including electrical and thermal conductivity of nanostructures, thermal rectification, and the role of ubiquitous material interfaces.
