Demonstration of direct bonding between InP andgadolinium gallium garnet (Gd 3 Ga 5 O 12 ) substrates

Abstract
The authors demonstrate the direct bonding of InP/Gd3Ga5O12 (GGG) and InP/GaInSb on GGG without glue. After chemical treatment, heat treatment was applied in an H2 atmosphere without a weight. This technique makes feasible the integration of semiconductor and magneto-optic devices.
