"new "2D" semiconductors made of single crystal layers,,, a class of materials known as transition-metal dichalcogenides... tungsten diselenide, to support the excitons. To create the acoustic waves for surfing, they placed that single-layer-semiconductor on a material that stretches and contracts in the presence of an electric field, lithium niobate. They used a set of electrodes on the lithium niobate to create a waving electric field"
