Schematics of the surface acoustic wave (SAW) chip for spectroscopic measurement. Hexagonal boron nitride (h-BN) powder is dispersed on the SAW path defined by a pair of interdigital transducers (IDTs, scale bar = 400 µm) lithographically patterned on a lithium niobate (LiNbO3) crystal. The x-axis of the laboratory reference frame corresponds to the SAW propagation direction. An optical microscope image of the dispersed h-BN powder (marked by a dotted red rectangle, scale bar = 50 µm) is superimposed on the chip layout
