Figure 1: System Schematic (IMAGE) Institute for Basic Science Caption Two interdigital transducers (IDTs) generate and detect surface acoustic waves (SAWs, orange arrow). In-between the IDTs, these waves interact with the electrons of a 2D material, such as molybdenum disulfide (MoS2), giving rise to conventional and unconventional acoustoelectric currents. MoS2 is separated from the piezoelectric substrate by a dielectric layer. Credit IBS Usage Restrictions Please indicate the credit.
