Abstract
The bonding mechanism between surfaces of tantalum and sapphire, aluminium and sapphire as well as copper and sapphire, was studied using optical reflectivity measurements and electro-reflection. In the tantalum-sapphire system, a reaction layer could be detected, but no indication of such a layer could be found in the other systems. The bond strengths observed in these systems are related to free valency states in the surfaces of the oxides.
