Review reveals advancements in Raman scattering characterization of group III-nitride semiconductors, highlighting its utility for diagnosing lattice strain, carrier transport, and defect structures.

Key Points

To review experimental progress in Raman scattering spectroscopy for GaN and related III-nitride semiconductors and identify future research directions.
Synthesized experimental developments in Raman scattering across binary (GaN, AlN, InN) and ternary (InGaN, AlGaN) compounds in both cubic and hexagonal phases.
Evaluated optical techniques used to measure lattice dynamics, strain, compositional fluctuations, impurities, and coupled LO phonon-plasmon modes.
Identified fundamental Γ-point phonon frequencies across cubic and hexagonal structures of GaN, AlN, and InN, enabling precise measurement of strain and alloy composition.
Demonstrated that coupled longitudinal optical phonon-plasmon modes in GaN provide effective non-destructive characterization of free-carrier transport properties.
Established foundational characterization methods currently being extended to low-dimensional structures, including nitride quantum dots and superlattices.
