Electrically driven nanoscale acoustic source based on a two-dimensional electron gas

Lei Shao, Meng Zhang, and Animesh Banerjee et al.

Acoustic emission by a modulated two-dimensional electron gas (2DEG) is studied analytically, numerically, and experimentally. Optical reflectance measurements provide the full acoustic spectrum emitted by a modulated GaN-based 2DEG, including various surface acoustic wave (SAW) modes that propaga ... [Appl. Phys.
