Claim:
1. A method for fabricating a composite structure including a layer to be separated by irradiation, the method comprising: forming a separation layer between the layer to be separated by irradiation and a support substrate at least partially transparent to a selected wavelength of radiation, the separation layer comprising a heating sublayer configured and formulated to produce heat upon exposure to the selected wavelength of radiation and an exfoliation sublayer configured and formulated to be weakened by the heat produced by the heating sublayer; and forming an antireflection layer at the interface between the support substrate and the separation layer so as to modify the reflective optical properties of the interface between the support substrate and the separation layer, and selecting a composition of the antireflection layer such that a refractive index of the antireflection layer is at least substantially equal to √{square root over (n
