▎ 摘　　要

NOVELTY - The apparatus (2) has a piezoelectric substrate (4) that is configured to propagate a surface acoustic wave (6) and a transducer (8) is coupled to the piezoelectric substrate. One graphene electrode (10) is configured to transduce a propagating surface acoustic wave to an electrical signal (11). USE - Apparatus for transducing surface acoustic wave to electrical signal in semiconductor device such as FET and Schottky diode. ADVANTAGE - The surface acoustic wave can be transduced to electrical signal to produce efficient alternating electrical output signal for high frequency operation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the apparatus for transducing surface acoustic wave. Apparatus for transducing surface acoustic wave (2) Piezoelectric substrate (4) Surface acoustic wave (6) Transducer (8) Graphene electrode (10) Electrical signal (11)
