Nanomechanical resonators made of two-dimensional (2D) materials, such as graphene, have been long believed to be the devices of choice for high-performance force and mass measurement. The limit of detection, defined as the smallest frequency shift that can be resolved with these devices, is intrinsically linked with frequency fluctuations which is one of the least understood problems in nanomechanical sensing. Many different mechanisms have been proposed as the underlying root cause of frequency fluctuations, among which the role of nonlinearities has been the least known. In this project, our goal is to engineer resonant sensors with optimal frequency stability. To achieve this, we plan to use nonlinear dynamic phenomena such as internal resonance to quench noise and enhance the stability of the 2D sensors. The project will combine theoretical and experimental nonlinear dynamics and will focus on fabrication, testing, and characterization of 2D nonlinear oscillators to tame frequency noise and obtain breakthrough nanomechanical performance.
The vacant position is in the Dynamics of Micro and Nanosystems (DMN) group. The group focuses on exploiting dynamics of small-scale systems to create technologies that can lead to new products in the fields of scientific instrumentation, consumer electronics and healthcare. Our research spans from measuring and manipulating materials at the micro and nano scale, to the design of world-class MEMS and NEMS sensors and actuators.
You will be working in an international environment in one of the leading technical universities of Europe, with access to state-of-the art micro-nano testing facilities and advanced numerical modelling tools. You will be contributing to a challenging topic related to a European Research Council (ERC) Consolidator grant together with a team of 3 PhD students and 2 postdocs.
As a postdoctoral researcher your tasks will include:

Challenge. Change. Impact!
From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.
ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
