项目摘要

In the previous year, the milestones set in the research plan has been acheived and published in academic journals. A highly repeatable, stable, and a reliable fabrication process for fabricating graphene nanoribbon(GNR) structures of ribbon width less than 70-nm has been established. Using this process methodology, GNR of width 30-nm can be patterned and structured on a device with stable electronic performance. The photonic properties of this device was tested under a solar simulator and two different wavelength of lights focused from a laser beam. When tested under a light beam of 532-nm, the device responded with a photonic responsivity of 5.5x10^3 (A/W) which is comparable and even larger than several graphene and GNR based devices in current literature. Secondly, the concept of controlling and further enhancing the electronic band properties of graphene nanoribbons by applied mechanical stress has also been tested and validated experimentally. The data showed a very high gauge factor of 1,500 under mechanical strain, which is also exceptionally larger than several metallic strain gauges. The concepts tested and validated in this research proves the feasibility of GNR structures application to high performing semiconductor devices. The data has been published in highly ranked academic journals and presented in two international conferences, in Japan and Portugal. In addition, the paper presented in Japan has received IEEE EPS Japan Chapter Award.

去年，研究计划中设定的里程碑已经实现并在学术期刊上发表。已经建立了一种高度可重复、稳定且可靠的制造工艺，用于制造带宽度小于70纳米的石墨烯纳米带（GNR）结构。使用这种工艺方法，可以在具有稳定电子性能的器件上对宽度为 30 nm 的 GNR 进行图案化和结构化。该设备的光子特性在太阳模拟器和激光束聚焦的两种不同波长的光下进行了测试。在 532 nm 光束下进行测试时，该器件的光子响应率为 5.5x10^3 (A/W)，与当前文献中的几种基于石墨烯和 GNR 的器件相当甚至更大。其次，通过施加机械应力来控制和进一步增强石墨烯纳米带电子带性能的概念也经过了实验测试和验证。数据显示，机械应变下的应变系数非常高，达到 1,500，这也比几种金属应变计大得多。本研究中测试和验证的概念证明了 GNR 结构应用于高性能半导体器件的可行性。这些数据已发表在排名较高的学术期刊上，并在日本和葡萄牙的两次国际会议上发表。此外，在日本发表的论文还获得了 IEEE EPS 日本分会奖。
