Abstract
Methods of fabricating dimensional silica-based substrates or structures comprising a porous silicon layers are contemplated. According to one embodiment, oxygen is extracted from the atomic elemental composition of a silica glass substrate by reacting a metallic gas with the substrate in a heated inert atmosphere to form a metal-oxygen complex along a surface of the substrate. The metal-oxygen complex is removed from the surface of the silica glass substrate to yield a crystalline porous silicon surface portion and one or more additional layers are formed over the crystalline porous silicon surface portion of the silica glass substrate to yield a dimensional silica-based substrate or structure comprising the porous silicon layer. Embodiments are also contemplated where the substrate is glass-based, but is not necessarily a silica-based glass substrate. Additional embodiments are disclosed and claimed.
