Keşkekler, A. (author)Micro and nanomechanical resonators are essential to the state-of-the-art communication, data processing, timekeeping, and sensing systems. The discovery of graphene and other two-dimensional (2D) materials has been a profound source of inspiration for the next generation of these devices, owing to their exceptional mechanical, electrical, and...doctoral thesis 2023

Keşkekler, A. (author), Arjmandi Tash, H. (author), Steeneken, P.G. (author), Alijani, F. (author)Nonlinearities are inherent to the dynamics of two-dimensional materials. Phenomena-like intermodal coupling already arise at amplitudes of only a few nanometers, and a range of unexplored effects still awaits to be harnessed. Here, we demonstrate a route for generating mechanical frequency combs in graphene resonators undergoing symmetry...journal article 2022

Dolleman, R.J. (author), Belardinelli, P. (author), Houri, S. (author), van der Zant, H.S.J. (author), Alijani, F. (author), Steeneken, P.G. (author)Stochastic switching between the two bistable states of a strongly driven mechanical resonator enables detection of weak signals based on probability distributions, in a manner that mimics biological systems. However, conventional silicon resonators at the microscale require a large amount of fluctuation power to achieve a switching rate in the...journal article 2019

Dolleman, R.J. (author)Micro and nanomechanical sensors are indispensable in modern consumer electronics, automotive and medical industries. Gas pressure sensors are currently the most widespread membrane-based micromechanical sensors. By reducing their size, their unit costs and energy consumption drops, making them more attractive for integration in new applications...doctoral thesis 2018
