Abstract
The scanning tunneling microscope (STM) after sophisticated modification is a powerful technique to investigate surface acoustic waves (SAWs) with high spatial resolution. Using our ultra high vacuum SAW-STM, a Rayleigh wave propagating in LiNbO3 has been characterized. In accordance with a previous model, the amplitude and phase signals extracted from the modulated tunneling current depend on the surface inclination and the eccentricity β of the SAW. From comparison with simulated amplitude and phase images a value for β=30–40° is obtained in good agreement with the theoretical eccentricity of the Rayleigh wave.
