From: Hexagonal boron nitride nanomechanical resonators with spatially visualized motion
Frequency scaling of circular drumhead hexagonal boron nitride (h-BN) resonators. (a–d) Resonance frequency and device thickness relations of the fundamental mode and first 3 splitting modes, respectively. Symbols indicate experimental data from optical interferometry measurements. Spatially mapped mode shapes (in experiments) are labeled with solid symbols, and predicted (from resonance sequences) values are indicated by hollow symbols. Insets: Corresponding node distribution illustration of each mode. (e) Waterfall plot of the four resonance modes.
