Tuning of crystal structure and electronic band gap of the monoclinic Ga₂O₃ by simultaneous alloying with Al₂O₃ and In₂O₃.

ABSTRACT: The paper presents the study of phase and structural behavior of pseudoternary compound (Ga_1-x-yIn_xAl_y)₂O₃ with focus on the compositional cross-section where the x/y ratio is a fixed at 0.31/0.69. This specific ratio ensures that the average cation radius, equal to that of Ga³⁺ ions, remains unchanged. Through the combination of experimental XRD studies and DFT calculations, the stability region of the monoclinic phase within the Ga₂O₃-Al₂O₃-In₂O₃ ternary system was established. Detailed analysis of the crystal lattice parameters and unit cell volume of the monoclinic structure was carried out across a wide range of compositions. An empirical relationship was
