Abstract

In the evolving landscape of unconventional computing, this review explores the nascent field of thermal computing. Thermal computers, which use heat as a computational element, present a significant shift from traditional computing paradigms. This review focuses on memory devices and logic gates that function via heat transfer mechanisms, exploring thermal computing’s potential to harness heat for computational purposes and expand the horizons of computing beyond conventional electronic paradigms. The motivation for this work stems from the need to expand the horizons of computing beyond conventional electronic systems-which have overshadowed all other forms of computing since the 20th century-leveraging the 72% of global primary energy lost in conversion processes. By harnessing the world’s ample amounts of waste thermal energy, one can envisage computational advancements in diverse areas such as self-powered systems, extreme environmental applications, and server farms, wherein thermal computing devices could synergistically interact with electronic systems. To address the gap in comprehensive studies on thermal computing’s engineering applicability and real-world integration, this review includes a detailed analysis of thermal memory devices and logic gates, evaluating their data retention, distinct states, and read/write speeds, alongside their scalability and potential real-world applications. A comprehensive technology readiness assessment for these devices underscores their potential and the challenges ahead in transitioning from theoretical constructs to practical tools. The outcomes of this assessment found that the Radiative Thermal Transistor score outperformed all other memory devices by 9.4% and the NanoThermoMechanical logic gates score outperformed other logic devices by 27%. To conclude, this review highlights the need for further advancement in thermal computing, underlining its potential to revolutionize computational models and expand the frontiers of information science. By integrating hysteresis and bistability with effective thresholding, thermal computing devices could provide stable, reliable, and efficient alternatives to electronic counterparts, leading to a seismic shift in computational technologies.
热二极管,晶体管和逻辑:非常规计算方法的回顾
在不断发展的景观非常规计算,这篇综述探讨了热计算的新兴领域。热计算机,使用热量作为计算元素,呈现出传统计算范式的重大转变。这篇综述的重点是通过传热机制起作用的存储设备和逻辑门,探索热计算在利用热量进行计算方面的潜力,并将计算的视野扩展到传统电子范式之外。这项工作的动机源于需要扩大计算的视野,超越传统的电子系统——自20世纪以来,传统电子系统已经掩盖了所有其他形式的计算——利用在转换过程中损失的72%的全球初级能源。通过利用世界上大量的废热能,人们可以设想在各种领域的计算进步,如自供电系统、极端环境应用和服务器场,其中热计算设备可以与电子系统协同交互。为了解决热计算工程适用性和现实世界集成综合研究的差距,本综述包括对热存储器件和逻辑门的详细分析,评估其数据保留,不同状态,读/写速度,以及其可扩展性和潜在的现实世界应用。对这些设备进行全面的技术准备评估,强调了它们从理论结构向实用工具过渡的潜力和挑战。这项评估的结果发现,辐射热晶体管的得分比所有其他存储器件高出9.4%,纳米热机械逻辑门的得分比其他逻辑器件高出27%。综上所述,本综述强调了热计算进一步发展的必要性,强调了其革命性计算模型和扩展信息科学前沿的潜力。通过将迟滞和双稳性与有效阈值相结合,热计算设备可以为电子设备提供稳定、可靠和高效的替代品,从而导致计算技术的巨大转变。
