论文摘要
这项工作提出了一种自动化的三分弯曲设备，可用于研究二维材料的应变工程和应变型。我们通过报告可重复的应变调整的微反射，拉曼和光致发光光谱来基准测试系统。这些结果与使用常规弯曲机器的文献非常吻合。我们进一步利用该系统通过测量压电效应和对MOS2电气设备中光增强响应的应变效应来自动化应变器件的应变研究。给出了直接系统构建的细节，我们预计它可以轻松地实施，以研究各种2D材料系统的应变工程和应变型。
This work presents an automated three-point bending apparatus that can be used to study strain engineering and straintronics in two-dimensional materials. We benchmark the system by reporting reproducible strain tuned micro-reflectance, Raman, and photoluminescence spectra for monolayer molybdenum disulfide (MoS2). These results are in good agreement with reported literature using conventional bending apparatus. We further utilize the system to automate strain investigations of straintronic devices by measuring the piezoresistive effect and the strain effect on photoresponse in an MoS2 electrical device. The details of the construction of the straightforward system are given and we anticipate it can be easily implemented for study of strain engineering and straintronics in a wide variety of 2D material systems.
