Webb31 jan. 2024 · This is a significant effect of the membrane stress on α × dn/dT. The effect on α only could be separately determined by measurement of (dn/dT) S. 4. Conclusion. We have measured the change in α × dn/dT of a silicon nitride membrane for increasing and decreasing stress by either heating the cSi frame or the membrane itself with a laser.
