Generation and control of ultrashort-wavelength two-dimensional surface acoustic waves at nanoscale interfaces
In this work, we generate and probe the shortest wavelength surface acoustic waves to date, at 45 nm, by diffracting coherent extreme ultraviolet beams from a suboptical phononic crystal. The short acoustic wavelengths correspond to penetration depths of approximately 10 nm. We also measure the acou...
