250 Oscillation of a nanodrum Tiny membranes are structured by arrangements of nanopillars so that they adopt vibrational modes with tailored properties. The nanopillars are missing in the 200 center of the membrane, meaning that the central area can vibrate with extremely low dissipation. This figure shows a measurement of the membrane’s vibration amplitude, which is very large in the center and becomes smaller toward the edges. The researchers use nanodrums such as these for quantum science, and the image was among the winners of the 2024 Nano Image Award.
