中文简介: | 在过去的十年中,最先进的硅基电子设备已经从100纳米或更高的设备发展到30纳米及以下的领域。为了解决业界在CMOS器件进一步扩展时所面临的功率问题,开发了一项名为Nanoelectronic Research Initiative的计划,以开发利用新状态变量的新材料和器件,以提高每功率密度的性能。石墨烯是一种排列在蜂窝状晶格中的单层碳原子,由于其独特的传输性质以及优异的化学和物理性质,最近受到了相当大的理论和实验兴趣。已经提出了利用关于在双层石墨烯膜,基于石墨烯的隧道FET,横向隧道FET和基于Veselago透镜的器件中存在玻色 - 爱因斯坦凝聚体的理论预测的新器件。然而,为了证明所提出的任何一种都能满足最基本的器件要求,必须开发高质量的薄膜并与电介质和金属触点集成。我们将回顾对CMOS以外的器件的需求,大面积石墨烯的增长以及电介质和金属触点与石墨烯的集成及其对场效应晶体管特性的影响。 |
课程简介: | In the past decade, the state-of-the-art silicon-based electronics has gone from devices at or above 100 nm to the realm of 30 nm and below. In order to address the power issues the industry is facing as CMOS devices are scaled further, a program called Nanoelectronic Research Initiative was created to develop new materials and devices that take advantage of new state variables with the objective of improving performance per power density. Graphene, a monolayer of carbon atoms arranged in a honeycomb lattice, has recently been subject of considerable theoretical and experimental interest because of its unique transport properties together with exceptional chemical and physical properties. New devices taking advantage of the theoretical prediction on the existence of a Bose-Einstein condensate in bi-layer graphene films, graphene based tunnel FETs, lateral tunnel FETs, and Veselago lens based devices have been proposed. However, in order to demonstrate that any of the proposed can meet the most basic device requirements, high quality films will have to be developed and integrated with dielectrics and metal contacts. We will review the need for devices beyond CMOS, growth of large area graphene and integration of dielectrics and metal contacts with graphene and their effects on field effect transistors characteristics. |
