In order to predict material failure accurately, it is critical to have knowledge of deformation physics. Uniquely challenging is determination of the conversion coefficient of plastic work into thermal energy. Here, we examine the heat transfer prob

Periodic porous structures offer unique material solutions to thermoelectric applications. With recent interest in phonon band gap engineering, these periodic structures can result in reduction of the phonon thermal conductivity due to coherent destr

Thermoreflectance techniques are powerful tools for measuring thermophysical properties of thin film systems, such as thermal conductivity, Λ, of individual layers, or thermal boundary conductance across thin film interfaces (G). Thermoreflectance p

The absorption of optical energy and subsequent thermal transport are investigated experimentally and numerically for 500 μm long, 250 μm wide, and 2.25 μm thick polycrystalline silicon microcantilevers irradiated by an 808 nm continuous-wave lase

Optical actuators are fundamental building blocks in the development of all-optical microelectromechanical devices. Photothermally actuated devices are inevitably limited by overheating and device damage resulting from the absorption of laser power.

Adhesion failure is a significant reliability concern and a major barrier to commercializing MEMS devices. In this paper, a beam-peel-based experimental setup was improved to measure the adhesion energy between a microcantilever and a substrate at di

Bent-beam, polycrystalline silicon MEMS thermal actuators were optically powered using laser illumination. The actuators were designed with a target suspended between angled legs that expand creating displacement and force when the target is heated b

Polycrystalline silicon (polysilicon) films are primary structural materials for microelectromechanical systems (MEMS). Due to relatively high compliance, large surface-to-volume ratio, and small separation distances, micromachined polysilicon struct

In this work, the use of Raman Stokes peak location and linewidth broadening methods were evaluated for thermometry applications of polysilicon microheaters subjected to evolving thermal stresses. Calibrations were performed using the temperature dep
