Figure Lengend Snippet: ( a ) Typical stress versus temperature curves of BiI 3 deposited on fused silica, 7059 Corning glass, 211 Precision glass and Z-cut quartz substrates; ( b ) derivatives of stress, extracted from ( a ), with respect to temperature (dσ/dT) of BiI 3 versus CTE (or α) of the substrates. The data are average of measurements performed in five films deposited in each substrate at different runs. The CTE and biaxial Young’s modulus of BiI 3 were extracted from the indicated fitting.

Article Snippet: The X-ray diffraction pattern (Fig. ) indicates that the films deposited on all substrates (Z-cut quartz, 〈111〉 silicon, 211 Precision glass, 7059 Corning glass and fused silica) have an R-3 rhombohedral crystal structure (JCPDS PDF # 48-1795) with a preferential orientation in the (003) direction.

Figure Lengend Snippet: Properties of fused silica, 〈111〉 silicon, 7059 Corning glass, 211 Precision glass, and Z-cut quartz substrates: coefficient of thermal expansion (CTE), Young’s modulus (E s ), Poisson’s ratio (ν s ), E s /(1 − ν s 2 ) calculated by using E s and ν s , reduced Young’s modulus E r = E s /(1 − ν s ²) and hardness (H) experimentally determined by nanoindentation, and thickness.
