Abstract
This work focuses on the thermalization and relaxation behaviors in ultrafast heat transport, ranging from sub- nanoseconds to picoseconds. The unique phenomena in thermal lagging, including ultrafast thermalization at short times, thermal exaggeration in amorphous materials, and thermal resonance in high-frequency excitations, are first summarized to draw special attention to the thermal design for ultrafast photonic devices. Temperature jumps across the interface between dissimilar materials follow, which include additional effects of phonon scattering in the interfacial area. Parameter groups are identified to characterize the temperature jumps to avoid the delamination damage due to thermal straining.
