Table 2
Elastic properties of TS-GaInP and CS-GaInP. Elastic constants C11 and C12 are calculated with Vegard’s law using values from Ref. 16 for binary compounds. The Poisson’s ratio is v = C12/(C11 + C12), and the Shear modulus is G = (C11 − C12)/2
Material	xIn	C11 (GPa)	C12 (GPa)	ν	G (GPa)
TS-GaInP	0.34	127.1	60	0.321	33.55
CS-GaInP	0.62	116.1	58.4	0.335	28.86
