摘要

The present paper proposes a simple method which may be able to provide true single-crystal films of complex oxides on large substrates including semiconductors like silicon or gallium arsenide. The method describes a layer transfer process using layer splitting by hydrogen implantation and direct wafer bonding (DWB) to obtain single-crystal oxide films on different substrates. Alternatively, a fabrication process of ferroelectric-semiconductor heterostructures based on direct wafer bonding and layer transfer is also described. This process is an alternative method to the direct wafer bonding and layer transfer is also described. This process is an alternative method to the direct deposition of oxides films (ferroelectric, high-k) on silicon and allows fabrication of metla oxide-silicon heterostructures with an interface having a good structural quality as well as a low trap density.
