説明:

Although β-Ga2O3 crystallizes in the monoclinic system, its structural complexity can be
simplified by focusing on the oxygen framework. The oxygen sublattice forms a cubic close-
packed arrangement, corresponding to a distorted face-centered cubic (fcc) structure defined
by lattice vectors: afcc = b + 1/2 c, bfcc = − b + 1/2 c, cfcc = 1/3 a + 1/6 c, giving lattice
parameters of afcc = bfcc = 4.20 Å, cfcc = 3.95 Å, αfcc = βfcc = 90.1°, γfcc = 92.7°. This pseudo-
cubic representation provides a straightforward understanding of the crystal shape, thereby
facilitating systematic exploration of its crystal orientations.
