Structure–property relationships are the foundation of materials science and are essential
for predicting material response to driving forces, managing in-service material degradation …

As is well-known, the phonon and electron thermal conductivity of a thin film generally
decreases as its thickness scales down to nanoscales due to size effects, which have …

An effective nondestructive testing technique that enables the detection and quantification of
surface and subsurface defects is highly demanded for assuring the safety and reliability of …

Microscale energy transport processes are crucial in microelectronics, energy-harvesting
devices, and emerging quantum materials. To study these processes, methods that can …

We extend time-domain imaging in acoustic metamaterials to gigahertz frequencies. Using a
sample consisting of a regular array of∼ 1 μm diameter silica microspheres forming a two …

Thermally conductive polymer crystals are of both fundamental and practical interest for their
high thermal conductivity that exceeds that of many metals. In particular, polyethylene fibers …

Direct mesoscale measurements of radiation-induced changes in the mechanical properties
of bulk materials remain difficult to perform. Most widely used characterization techniques …

Epitaxial growth of III-V semiconductors on Si is a promising route for silicon photonics.
Threading dislocations and the residual thermal stress generated during growth are …

We demonstrate the agreement between first-principles calculations and experimental
measurements of size effects in thermal transport in SiGe alloys without fitting parameters …

X-ray reflectivity measurements of femtosecond laser-induced transient gratings (TG) are
applied to demonstrate the spatiotemporal coherent control of thermally induced surface …
