Abstract
A method is provided for fabricating a substrate for optics, electronics, or optoelectronics. This method includes the steps of transferring a seed layer to a support layer, depositing a working layer onto the seed layer to form a composite substrate and detaching the working layer and the seed layer from the support to form a substrate. Advantageously, the support substrate comprises a material having a thermal expansion value of about 0.7 to 3 times the coefficient value of the working layer.
