As electronics get smaller and more powerful, the components within them that handle heat dissipation must also evolve. Increasing power density and rising hot spots must be accouted for and handled. In this PhD dissertation, the author studies materials for potential use as heat spreaders or insulators at the nanoscale to understand their thermal properties. Nanostructured superlattices have shown to be highly effective in reducing the thermal conductivity of heat ...
As electronic devices approach nanometer scales, heat distribution becomes nonuniform and hot spots begin to form. Integrating graphene into nanoelectronics enhances thermal conductivity and heat flow which mitigates hot spots. In this experiment, large quantities of graphene were produced and thermal conductivity was measured by the transient plane source (TPS) method using an instrument. Results showed that the addition of graphene greatly improved the thermal conductivity of the thermal interface ...
