Poot, M. (author)This thesis describes experiments that were done with a wide range of nano(electro)mechanical systems (NEMS). These devices are promising candidates to study mechanics in the quantum regime. The experiments range from AFM measurements on few-layer graphene nanodrums, electrical detection of flexural modes of suspended carbon nanotubes both at...doctoral thesis 2009

Van Leeuwen, R. (author)In this thesis the physics of nanoscale mechanical resonators and oscillators is studied. We discuss two types of resonators. First, a top-down fabricated doubly clamped beam resonator with an integrated piezoelectric actuator is introduced. The second type of resonators are based on layered two-dimensional materials, such as graphene and...doctoral thesis 2015

Siskins, M. (author)This thesis studies higher-order material properties* and effects in van der Waals crystals, such as anisotropic Young’s modulus, magnetostriction, and non-trivial thermal expansion effects near magnetic and electronic phase transitions, that can affect the nanomechanical motion ofmultilayer two-dimensional (2D) material membranes. These...doctoral thesis 2021

Lee, M. (author)This thesis encompasses both applied and fundamental studies of suspended van der Waals materials. Chapters 1 and 2 give an introduction to the field of 2D materials and some of the critical methods which facilitate the study of the suspended structures. In Chapters 3 and 4 we focus on the applications of graphene in barometric pressure sensors...doctoral thesis 2021

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

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

Davidovikj, D. (author), Bouwmeester, Damian (author), van der Zant, H.S.J. (author), Steeneken, P.G. (author)We report on the development of a pneumatically coupled graphene membrane system, comprising of two circular cavities connected by a narrow trench. Both cavities and the trench are covered by a thin few-layer graphene membrane to form a sealed dumbbell-shaped chamber. Local electrodes at the bottom of each cavity allow for actuation of each...journal article 2018

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
