Mechanical Manipulation of 2D Materials with Surface Acoustic Waves

ORAL

Abstract

High amplitude surface acoustic waves (SAWs) are a promising tool for the mechanical manipulation of 2D materials. Using 100 MHz surface acoustic waves on ST-cut quartz we have observed the SAW induced wrinkling and dewrinkling of hBN flakes. By modulating the phase of a standing surface acoustic wave, we have been able to laterally slide an hBN flake by many times the SAW wavelength. The promise of this technique is that it lives between the length scales of AFM manipulation (~10 nm) and of stamps/cantilevers (~100 microns), and that the in-situ nature of the technique allows easy integration with other tools (e.g. light microscopes, SPM, etc).
