Offer Description

The project aims at optimizing the performance of NEMS-based clocks by finding an appropriate balance between all the constraints including the mechanical structure design, the electrical actuation of this structure and the oscillator interface, with a novel approach. This novel approach is depicted in Fig. 3. Objective 1 – Provide an experimental demonstration of the use of specific waveforms in NEMS resonators to evade different types of fluctuations, to enhance the frequency stability of devices such as FM (frequency-modulated) sensors, without sacrificing drive efficiency. Objective 2 – Design and fabrication of a new NEMS structure optimized with system-level constraints. We will increase the number of degrees-of-freedom for phase noise minimization compared to objective 1 which only addresses the system level. In objective 2, we aim at incorporating the resonator design into the global optimization.

Requirements

Specific Requirements

This multidisciplinary project involves several fields including: - Applied mathematics and signal processing: pulsed and complex waveforms, associated spectrum. - Mechanics: linear and nonlinear resonators. Analytical modeling and FEM simulations. - Electronics: o Oscillators o Test benches including waveform generators, lock-in amplifiers, oscilloscopes, computer interface, etc. o PCB circuits design - Clean room fabrication processes: lithography, etching, microscope observations, optical characterization of nanostructures in motion, etc. It is obviously not required for the candidate to be already familiar with all these topics, but she/he must be motivated and interested to investigate all these aspects. Knowledge of programming/computing languages such as MATLAB/Simulink, Mathematica and/or Python would be a plus.
