Article "Thickness dependent stresses and thermal expansion of epitaxial LiNbO3 thin films on C-sapphire"

HIGHLIGHTS

• Identification of (0112) system twins in LiNbO3 films by means of XRD.
• Stress relaxation by mechanical twinning in LiNbO3 thin films.
• Tunning of in-plane and out-of-plane thermal expansion of thin films.
• Better understanding of the relaxation mechanisms and residual stresses.
• Relationship between clamped thermal expansion and film thickness.
