The atomic structures of liquid-phase bonded heterointerfaces between Al alloy and AlN single crystal was examined using aberration-corrected scanning transmission electron microscopy combined with high-sensitive energy-dispersive X-ray microanalysis. The formation of O-Mg-O monolayer structure was found at the interface, facilitating the bonding between the two dissimilar crystals during liquid-phase bonding processes. Understanding the spontaneous formation of such layered transition structures at the heterointerfaces will be a key for fabricating very stable liquid bonded Al alloy / AlN heterointerfaces.
