Abstract: A method of fabricating a power semiconductor device includes forming a bi layer mask on a semiconductor substrate, where the bilayer mask comprises a first dielectric layer on the semiconductor substrate and a second dielectric layer on the first dielectric layer. The first and second dielectric layers are through-etched to define an exposed portion of the semiconductor substrate. The first dielectric layer is selectively etched to form an undercut region of the bi layer mask. A crystalline semiconductor material is epitaxially grown on the exposed portion of the semiconductor substrate, and a polycrystalline semiconductor material is deposited on the second dielectric layer of the bilayer mask. After the epitaxial growth, the bilayer mask and the polycrystalline semiconductor material are removed from the semiconductor substrate, leaving behind a mesa comprising the crystalline semiconductor material on the semiconductor substrate.

In general, the metamaterial can be a metasurface, which may be flexible, having a periodic array of resonators.

Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.
