Abstract : Advances in semiconductor technology have increased heat dissipation in electronic devices, where efficient thermal management is crucial to prevent malfunctions and extend component lifetimes. A key strategy involves using thermal interface materials (TIMs) to enhance heat transfer between cooled components and heat sinks. However, as device sizes shrink, the thermal resistance at component-TIM interfaces becomes increasingly significant.

This presentation briefly mentions our group's work in modifying solid-liquid interactions to reduce interfacial thermal resistance, where the effects of surface morphology, crystal orientation, surfactant molecules, and self-assembled layers on heat transfer properties are demonstrated. A greater detail is also given on developed computational methods for estimating heat flux, computing work of adhesion, and modeling interfacial transport, which provide new insights into optimizing thermal management solutions.
