WebΔEa is associated with the carrier density and thus the strain or strained interfacial layer thickness in the Poly- or Epi-VO2. The larger tensile strain or thicker strained layer leads to lower carrier density and higher ΔEa, while the constant strain produces saturated ΔEa. ... quartz and Zerodur, a glass with low thermal expansion ... Zerodur has both an amorphous (vitreous) component and a crystalline component. Its most important properties are: • Particularly low thermal expansion: in the range 0 to 50 °C it has a mean of 0 ± 0.007×10 K , which is two orders of magnitude better than that of fused quartz. • High 3D homogeneity with few inclusions, bubbles and internal stria (as contrasted to Cer-Vit).
