Fabrication of two dimensional MoS2 sensors for piezoelectric applications

With the growing popularity of miniaturization of high performance piezoelectric devices, the research on applications of Transition Metal Dicalcogenide (TMD) mono layers has also grown a lot. This is because of the suitable piezoelectric properties exhibited by these two dimensional materials. In this project, a piezoelectric sensor, which could be used for various applications, is being designed which could receive both low and high frequency signals well. This project is in collaboration with Think Sensor Research, an organization working towards the development of marine and aerospace sensor applications. The present version of this device, which is being used by the collaboration company, possesses Lead zirconate titanate (PZT) as the piezoelectric material. Our purpose was to design and fabricate this device using Molybdenum Disulfide (MoS2) instead of PZT and observe the response and piezoelectric properties of the device.
