The study aims to differentiate between the hexagonal and monoclinic phases of GaTe using second harmonic generation techniques.
Used second harmonic generation to analyze the crystallization of GaTe phases.
Compared optical properties of h-GaTe and m-GaTe.
Conducted measurements to identify phase-specific characteristics.
Successfully identified distinct optical signatures for h- and m-GaTe.
Revealed that the phases exhibit differences in electronic properties.
Concluded that second harmonic generation is an effective method for phase detection.
Abstract
Two-dimensional (2D) GaTe is a recently synthesized III–VI semiconductor that can crystallize in either a hexagonal (h) phase or a monoclinic (m) phase, and these two phases show clearly different...
