Abstract

We report on the layer transfer of thin ferroelectric materials onto silicon substrates. H+ and He+ ion implantation created a buried sacrificial layer in the c-cut BaTiO3 and LiNbO3 single crystals. Bubble formation and thermodynamics of cavity at the bonding interface have been investigated, and single crystal thin film layers were transferred onto crystalline silicon substrates. We have found that defects generated by ion implantation in ferroelectric materials can be significantly recovered with the subsequent annealing for layer splitting.
