Abstract: The present invention uses a treatment that involves an etching treatment that forms a pnictogen-rich region on the surface of a pnictide semiconductor film The region is very thin in many modes of practice, often being on the order of only 2 to 3 nm thick in many embodiments. Previous investigators have left the region in place without appreciating the fact of its presence and/or that its presence, if known, can compromise electronic performance of resultant devices. The present invention appreciates that the formation and removal of the region advantageously renders the pnictide film surface highly smooth with reduced electronic defects. The surface is well-prepared for further device fabrication.

Abstract: Photovoltaics configured to be manufactured without epitaxial processes and methods for such manufacture are provided. Methods utilize bulk semiconducting crystal substrates, such as, for example, GaAs and InP such that epitaxy processes are not required. Nanowire etch and exfoliation processes are used allowing the manufacture of large numbers of photovoltaic cells per substrate wafer (e.g., greater than 100). Photovoltaic cells incorporate electron and hole selective contacts such that epitaxial heterojunctions are avoided during manufacture.

Abstract: The optical response of a metasurface is controlled by actuating it via an electrical or magnetic field, temperature control, optical pumping or electromechanical actuation. The metasurface will therefore control the polarization of the incident light. The metasurface comprises an array of patch antennas. The patch antennas are in the form of asymmetrical elements, including rotated rods, cross-shapes, V-shapes, and L-shapes.

Abstract: Electrically tunable metasurfaces including an array of subwavelength metasurface unit elements are presented. The unit elements include a stacked metal-insulator-metal structure within which an active phase change layer is included. A purely insulator, metal, or coexisting metal-insulator phase of the active layer can be electrically controlled to tune an amplitude and phase response of the metasurfaces. In combination with the subwavelengths dimensions of the unit elements, the phase and amplitude response can be controlled in a range from optical wavelengths to millimeter wavelength of incident light. Electrical control of the unit elements can be provided via resistive heating produced by flow of current though a top metal layer of the unit elements. Alternatively, electrical control of the unit elements can be provided via electrical field effect produced by applying a voltage differential between the top and bottom metal layers of the unit elements.
