The graphene squeeze-film microphone
M. P. Abrahams, J. Martinez, P. G. Steeneken +1
Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-in…
Optomechanical methodology for characterizing the thermal properties of 2D materials
Hanqing Liu, Hatem Brahmi, Carla Boix-Constant +3
Heat transport in two-dimensions is fundamentally different from that in three dimensions. As a consequence, the thermal properties of 2D materials are of great interest, both from…
Quantifying stress distribution in ultra-large graphene drums through mode shape imaging
Ali Sarafraz, Hanqing Liu, Katarina Cvetanović +6
Suspended drums made of 2D materials hold potential for sensing applications. However, the industrialization of these applications is hindered by significant device-to-device varia…
Ultra-sensitive graphene membranes for microphone applications
Gabriele Baglioni, Roberto Pezone, Sten Vollebregt +8
Microphones exploit the motion of suspended membranes to detect sound waves. Since the microphone performance can be improved by reducing the thickness and mass of its sensing memb…
Nanoelectromechanical Sensors based on Suspended 2D Materials
Max C. Lemme, Stefan Wagner, Kangho Lee +9
The unique properties and atomic thickness of two-dimensional (2D) materials enable smaller and better nanoelectromechanical sensors with novel functionalities. During the last dec…
Detecting Ultrasound Vibrations by Graphene Resonators
G. J. Verbiest, J. N. Kirchhof, J. Sonntag +3
Ultrasound detection is one of the most important nondestructive subsurface characterization tools of materials, whose goal is to laterally resolve the subsurface structure with na…
