This book investigates the intricate interplay between electrical, mechanical, and optical waves within III-nitride materials, focusing on surface acoustic waves (SAW) and acousto-optical (AO) effects. The authors explore the unique properties of materials like aluminum nitride, gallium nitride, and indium nitride, which enable operation under extreme conditions and facilitate the development of advanced light sources and detectors. The study specifically details the propagation of Rayleigh-type and leaky surface acoustic waves in bulk and layered nitrides, and examines the acousto-optic diffraction of guided optical waves from these SAWs in AlxGa1-xN-on-sapphire structures, leading to the determination of elastic and piezoelectric constants for AlN and highlighting the potential for deep UV AO applications.

This work presents a detailed scientific investigation into the acousto-optical properties of III-nitrides, a field critical for advanced optoelectronic devices. The research offers specific data on wave propagation and diffraction, contributing to the understanding of material constants and potential applications in deep UV technologies. The findings suggest a specialized text for researchers and engineers in solid-state physics and materials science.
