This paper presents a new concept for an acoustic diode driven by a phonon laser and asymmetric conductivity in piezoelectric semiconductor materials. This device utilizes high-amplitude acoustic waves to generate a unidirectional electric current, exploiting the directional properties of acoustic fields to induce rectification. The paper explores the fundamental theoretical model, potential applications, and feasibility of this technology for energy harvesting, acoustic sensors, and communication systems.
