Claim 25:
26. An electrical device, comprising:
a heat-generating component defining a first thermal-interface surface;
a heat-transfer component defining a second thermal-interface surface, wherein the first thermal-interface surface and the second thermal-interface surface are positioned opposite to each other, defining a thermal interface between the heat-generating component and the heat-transfer component, wherein the thermal interface between the heat-generating component and the heat-transfer component comprises a first region having an outer periphery and a second region surrounding the outer periphery of the first region;
a composite thermal-interface material within the thermal interface between the heat-generating component and the heat-transfer component, the composite thermal-interface material comprising a silicone oil substrate and a metallic filler comprising gallium, the metallic filler having a solid-to-liquid transition temperature between about 10° C. and about 95° C., wherein the composite thermal-interface material is positioned within the outer periphery of the first region; and
a second thermal-interface material within the second region, wherein a composition of the composite thermal-interface material differs from a composition of the second thermal-interface material and a ratio of volume resistivity of the second thermal-interface material to a volume resistivity of the composite thermal-interface material exceeds about 104.
