  • Publication number: 20110308583
    Abstract: Open circuit voltage of a photovoltaic device including a p-i-n junction including amorphous silicon-containing semiconductor materials is increased by a high power plasma treatment on an amorphous p-doped silicon-containing semiconductor layer before depositing an amorphous intrinsic silicon-containing semiconductor layer. The high power plasma treatment deposits a thin layer of nanocrystalline silicon-containing semiconductor material or converts a surface layer of the amorphous p-doped silicon containing layer into a thin nanocrystalline silicon-containing semiconductor layer. After deposition of an intrinsic amorphous silicon layer, the thin nanocrystalline silicon-containing semiconductor layer functions as an interfacial nanocrystalline silicon-containing semiconductor layer located at a p-i junction.

  • Publication number: 20110308584
    Abstract: A tunneling layer is provided between a transparent conductive material and a p-doped semiconductor layer of a photovoltaic device. The tunneling layer is comprised of stoichiometric oxides which are formed when an upper surface of the transparent conductive material is subjected to one of the surface modification techniques of this disclosure. The surface modification techniques oxidize the dangling metal bonds of the transparent conductive material. The tunneling layer acts as a protective layer for the transparent conductive material. Moreover, the tunneling layer improves the interface between the transparent conductive material and the p-doped semiconductor layer. The improved interface that exists between the transparent conductive material and the p-doped semiconductor layer results in enhanced properties of the resultant photovoltaic device containing the same. In some embodiments, a high quality single junction solar cell can be provided by this disclosure that has a very well defined interface.

  • Patent number: 8035173
    Abstract: An NFET containing a first high-k dielectric portion and a PFET containing a second high-k gate dielectric portion are formed on a semiconductor substrate. A gate sidewall nitride is formed on the gate of the NFET, while the sidewalls of the PFET remain free of the gate sidewall nitride. An oxide spacer is formed directly on the sidewalls of a PFET gate stack and on the gate sidewall nitride on the NFET. After high temperature processing, the first and second dielectric portions contain a non-stoichiometric oxygen deficient high-k dielectric material. The semiconductor structure is subjected to an anneal in an oxygen environment, during which oxygen diffuses through the oxide spacer into the second high-k dielectric portion. The PFET comprises a more stoichiometric high-k dielectric material and the NFET comprises a less stoichiometric high-k dielectric material. Threshold voltages of the PFET and the NFET are optimized by the present invention.

  • Publication number: 20110153299
    Abstract: Provided is a method of simulating various viscoelastic fluids having viscosity, elasticity, and plasticity, based on smoothed particle hydrodynamics (SPH), which is widely used in fluid simulation using particles. Artificial forces related with viscosity, elasticity, and plasticity are added to address fundamental numerical limitations of a SPH method due to use of particle approximation and to improve expression of characterized motions of a viscoelastic fluid. Since the artificial forces are added, and parameters are adjusted according to the adding of the artificial forces, a fluid can be realistically expressed, and the control of a fluid motion is facilitated.

    Abstract: A vertical stack of a first silicon germanium alloy layer, a second epitaxial silicon layer, a second silicon germanium layer, and a germanium layer are formed epitaxially on a top surface of a first epitaxial silicon layer. The second epitaxial silicon layer, the second silicon germanium layer, and the germanium layer are patterned and encapsulated by a dielectric cap portion, a dielectric spacer, and the first silicon germanium layer. The silicon germanium layer is removed between the first and second silicon layers to form a silicon germanium mesa structure that structurally support an overhanging structure comprising a stack of a silicon portion, a silicon germanium alloy portion, a germanium photodetector, and a dielectric cap portion. The germanium photodetector is suspended by the silicon germanium mesa structure and does not abut a silicon waveguide. Germanium diffusion into the silicon waveguide and defect density in the germanium detector are minimized.

  • Patent number: 7749847
    Abstract: A p-type field effect transistor (PFET) and an n-type field effect transistor (NFET) are formed by patterning of a gate dielectric layer, a thin silicon layer, and a silicon-germanium alloy layer. After formation of the source/drain regions and gate spacers, silicon germanium alloy portions are removed from gate stacks. A dielectric layer is formed and patterned to cover an NFET gate electrode, while exposing a thin silicon portion for a PFET. Germanium is selectively deposited on semiconductor surfaces including the exposed silicon portion. The dielectric layer is removed and a metal layer is deposited and reacted with underlying semiconductor material to form a metal silicide for a gate electrode of the NFET, while forming a metal silicide-germanide alloy for a gate electrode of the PFET.

  • Publication number: 20100161298
    Abstract: A method for calculating a force acting on an interface between immiscible fluids in an SPH (Smoothed Particle Hydrodynamics) based fluid simulation includes: calculating a force caused by viscosities of the fluids; calculating a force caused by pressures of the fluids; calculating an external force applied to the fluids from outside; and calculating an interactive force caused by interaction between the fluids. The force acting on the interface between the immiscible fluids are obtained by using sum of the force caused by the viscosities, the force caused by the pressures, the external force and the interactive force. The interactive force is a surface tensional force calculated based on a pressure acting on the interface between the fluids.
