摘要

对电子器件小型化的需求促进了石墨烯基混合结构的发展，其中包括金属-半导体-金属(MSM)器件。在这项工作中，有人通过在镍上生长单层石墨烯来形成基本结构基质，从而开发了这样一种装置。已经开发了四种不同的MSM单元结构变体，以评估它们在下一代电子产品中的潜力。通过原子力显微镜证实了石墨烯在原始基体中的存在，并利用紫外-可见-近红外光谱椭偏仪进一步研究了石墨烯层的光学响应;采用Forouhi-Bloomer模型对椭偏数据进行分析。通过霍尔效应和其他电学特性测量来分析所制备器件的电学性能。

Fabrication and characterization of graphene induced Metal Semiconductor Metal (MSM) structure for detection and sensing applications

The demand for miniaturization of electronic devices has lent to the development of graphene-based hybrid structures, which include the Metal-Semiconductor-Metal (MSM) device. In this work, one has developed such a device by growing monolayers of graphene on top of Nickel to form the basic structural matrix. Four different variants of the MSM unit structures have been developed to assess their potential in next generation electronics. The presence of graphene in the original matrix was confirmed via Atomic Force Microscopy, and the optical response of the graphene layer was further studied using Spectroscopic Ellipsometry in UV-Vis-NIR regime; Forouhi-Bloomer model was used to analyze the ellipsometry data. Hall effect and other electrical characterization measurements were conducted to analyze the electrical properties of the fabricated devices.
