The thermo-mechanical properties of silicon make it of significant interest as a possible material for mirror substrates and suspension elements for future long-baseline gravitational wave detectors.Abstract:
The thermo-mechanical properties of silicon make it of significant interest as a possible material for mirror substrates and suspension elements for future long-baseline gravitational wave detectors. The mechanical dissipation in 92 μm thick 〈110〉 single-crystal silicon cantilevers has been observed over the temperature range 85 K to 300 K, with dissipation approaching levels down to ϕ=4.4×10−7.read more

Theory of Thermoelastic Damping in Micromechanical Resonators With Two-Dimensional Heat Conduction
TL;DR: In this paper, an exact theory for TED with 2-dimensional heat conduction was presented, which enables a detailed evaluation of the accuracy of the quasi-1-D theories for low-loss vacuum-operated micro-and nanomechanical resonators used in microelectro- mechanical systems.
Thermoelastic Damping in Micro- and Nano-Mechanical Systems.

Abstract: The importance of thermoelastic damping as a fundamental dissipation mechanism for small-scale mechanical resonators is evaluated in light of recent efforts to design high-Q micrometer- and nanometer-scale electromechanical systems. The equations of linear thermoelasticity are used to give a simple derivation for thermoelastic damping of small flexural vibrations in thin beams. It is shown that Zener’s well-known approximation by a Lorentzian with a single thermal relaxation time slightly deviates from the exact expression.

Exponential Temperature Dependence of Young's Modulus for Several Oxides
TL;DR: In this paper, Young's modulus was measured over the temperature range 77\ifmmode^\circ\else\textdegree\fi{}-850\ifmodesode^ \circ\ else\text degree{}k by an accurate resonance technique, and the results showed that the range of validity of a temperature dependence predicted by theory must be quite small.
