  • Patent number: 11328950
    Abstract: Embodiments of the disclosure relate to a method for fabricating semiconductor-on-insulator (SemOI) electronic components. In the method, a device wafer is bonded to a handling wafer. The device wafer includes a semiconductor device layer and a buried oxide layer. A substrate is adhered to the handling wafer. The substrate is a glass or a ceramic, and bonding occurs at an interface between the semiconductor device layer and the substrate. Material is removed from the device wafer to expose the buried oxide layer. The substrate is debonded from the handling wafer so as to provide an SemOI electronic component including the substrate, the semiconductor device layer, and the buried oxide layer.

  • Patent number: 9183993
    Abstract: A one-pot synthesis of Nb5+-doped TiO2 nanoparticles (NPs) with low cost and high efficiency for dye sensitized solar cells (DSSCs) is disclosed in the present invention. The Nb5+-doped TiO2 NPs with Nb dopants of 0˜5 mol % are prepared by directly mixing TiO2 slurry with Nb2O5 gel obtained by UV treatment of a mixture of NbCl5 powder, ethanol and water in a certain ratio, following by heat treatment without using hydrothermal method. The as-prepared NPs exhibit well-crystallized pure anatase TiO2 phase with uniform particle distribution. The incorporation of Nb5+ leads to a stronger and broader light absorption in visible light range and a decrease of band gap with increasing Nb dopant content, which enhances the efficiencies of light-harvesting and electron injection and suppresses the charge recombination. The present method provides a simple and cost-effective mass-production route to synthesize n-type metallic ion doped TiO2 nanoparticles as excellent photoanode materials.
