1.Introduction:
Thecontinuousminiaturizationofelectronicdevicesandtheincreasingdemandforeffectivethermalmanagementhavedriventheneedforadvancedmaterialswithexcellentthermalconductivity.Amongvariousmaterials,diamondstandsoutasanexceptionalthermalconductor.However,itshighcostandlimitedavailabilityrestrictitswidespreadapplication.Toovercomethesechallenges,sandwichcompositestructureshavebeendeveloped,combiningtheadvantagesofdiamondwithmoreaffordablematerials.Inthisstudy,analuminum-silicon-aluminumdiamond-aluminum-siliconsandwichcompositestructurewaspreparedandevaluatedforitsthermalconductivityproperties.
