  • Publication number: 20180108525
    Abstract: A method is disclosed for depositing a high-quality thin films of ultrawide bandgap oxide semiconductors at growth rates that are higher than possible using prior-art methods. Embodiments of the present invention employ LPCVD deposition using vapor formed by evaporating material as a precursor, where the material has a low vapor pressure at the growth temperature for the thin film. The vapor is carried to a reaction chamber by an inert gas, such as argon, where it mixes with a second precursor. The reaction chamber is held at a pressure that nucleation of the precursor materials occurs preferentially on the substrate surface rather than in vapor phase. The low vapor pressure of the material gives rise to growth rates on the substrate surface that a significantly faster than achievable using prior-art growth methods.

  • Publication number: 20150280867
    Abstract: The present disclosure discloses a method and a system applied in a Physical Uplink Shared Channel (PUSCH) Hybrid Automatic Repeat Request (HARQ) timing for Carrier Aggregation (CA). when a Round-Trip Time (RTT) of a scheduling cell is not equal to 10 ms, an HARQ of the PUSCH on a scheduled cell may follow a timing mode of a time slot configuration of config#1 defined by the 3rd Generation Partnership Project (3GPP). By using the solution according to the present disclosure, it is ensured that there is at least one sub-frame being able to work properly in the PUSCH on the scheduled cell and the transmission efficiency is maximized except for two circumstances where the time slot configuration of the scheduling cell and the time slot configuration of the scheduled cell are (config#6, config#0) and (config#0, config#6) defined by the 3GPP.

  • Publication number: 20150241056
    Abstract: Systems and methods are provided for enhancement of gaseous CLC in a fixed-bed process, marked by an increase in CO2 capture efficiency and oxygen carrier utilization, while reducing disadvantages of a conventional fixed-bed operation. The disclosed systems/methods provide a CLC fixed-bed reactor design in which the direction of the fuel gas is intermittently reversed during a single fuel oxidation step. In this reverse-flow mode, oxygen carrier reduction reactions are displaced over the ends of the reactor, which increases contact between fuel and oxidized solids and alleviates and/or mitigates problems of carbon deposition encountered by most oxygen carriers.
