Project Description


Project description:

Introduction:
Nanoelectromechanical systems (NEMS) is a fast-growing field of research which reaches beyond the established microelectromechanical systems (MEMS) by shrinking structure sizes to the nanoscale. The field thereby encompasses several areas of knowledge including continuum mechanics, dynamics and acoustics, optics, electromagnetism and quantum mechanics. It relies on the investigation of freely suspended nanostructures like nanostrings or nanomembranes, which have been processed using state of the art nanofabrication and cleanroom technology to enable vibrations, like those of a guitar string or a drumhead, which can be controlled by means of electromagnetic fields. The work of the Chair of Nano and Quantum Sensors focuses mainly on the coupling between mechanical and electromagnetic or optical resonators. This coupling takes place in a dynamical fashion, that is for instance when the controlled oscillation of the electromagnetic/optical field acts back on the mechanical vibration, allowing to control its dynamics.

Tasks and learning outcomes:
In this project, the students are expected to learn about the physics underlying this dynamical coupling both mathematically and experimentally and obtain a real hands-on experience. In particular, the student will learn how to mathematically model the system under study, help in preparing the test rig, and assist in fabricating the nanosystems if required. Furthermore, the student will learn about the evaluation of the measurement data, and will be able to discuss the results and present them, which provides a rich experience about most of the research process. Moreover, the students will enhance their team working and communication skills by engaging in discussions with the team, and most importantly, they will enhance their critical thinking capabilities on a scientific basis.

Working hours per week planned:
