Epitaxial thin film transfer for flexible devices from reusable substrates

A new epitaxial thin film transfer method is introduced which utilizes film/substrate systems with sufficiently strong interaction for heteroepitaxial alignment, but with weak adhesion interaction such that inherent stress caused by heteroepitaxy combined with thermomechanical stress causes the deposited structures to separate at the interface. The thin films retain their optical and structural properties following the transfer process to a …
