High-efficiency bandwidth product germanium photodetector

InactiveUS20140159183A1Sacrifice efficiencyHigh-efficiency bandwidthPhotovoltaic energy generationSemiconductor devicesHigh bandwidthResonant cavity
A high-efficiency bandwidth product germanium photodetector includes a silicon substrate having an opening-down three-sided groove formed by etching; a metallic reflective mirror layer formed by plating along an internal periphery of the opening-down three-sided groove of the silicon substrate; a light absorbent layer between the metallic reflective mirror layer and a dielectric reflective mirror layer. The light absorbent layer can be p-i-n type or other types. By the use of the critical coupling of resonant cavity, all the incident lights can be completely obstructed in the cavity between the metallic reflective mirror layer and the dielectric reflective mirror layer to reach a critical coupling which means 100% absorption efficiency can be achieved without light leakage. Thus on the basis of the critical coupling, the trade-off between bandwidth and efficiency can be broken through to reach high responsivity and high bandwidth up to 50 GHz by decreasing the germanium layer thickness without sacrificing the light-switch-to-electro absorption efficiency.

Paper corner protector

A paper corner protector includes a corner reinforcement body (1) which consists of a cardboard (2) and a cavity (3), wherein the cavity (3) is formed by folding the cardboard (2) end to end. The present utility model enhances the convenience of cost during its transportation and decreases its storage space. Furthermore, a Kraft board is used as the raw material, which is recoverable and reusable and has water-absorbing capacity, so it meets the requirement of environmental protection. It can be expediently folded to become packaging corner protectors so as to be placed on the corners of a packing container such that it can provide favorable protective actions to the corners of the product in the container, such as buffer action, shockproof action and moisture proof action.

Recombinant H5N1 (Hemagglutinin 5 Neuraminidase 1) avian influenza virus cell vaccine and application thereof

The invention relates to the technical field of animal infectious diseases, in particular to a recombinant H5N1 (Hemagglutinin 5 Neuraminidase 1) avian influenza virus cell vaccine and an application thereof. The recombinant H5N1 avian influenza virus cell vaccine comprises a recombination H5N1 avian influenza virus rC4 / W1 strain which is collected in the China Center for Type Culture Collection with the collection number of CCTCC NO:V201029; and a genome of the recombinant H5N1 avian influenza virus rC4 / W1 strain contains fragments shown as SEQ ID NO:1-8 of eight relevant genes of an avian influenza virus. The recombinant H5N1 avian influenza virus is saved by using a reverse genetics method, and the recombination virus is passaged to stable on an MDCK (Madin Darby Canine Kidney) cell and is taken as an oil emulsion inactivated vaccine after being inactivated. H5N1 subtype avian influenza virus HA (Hemagglutinin) and NA (Neuraminidase) genes are replaced on the background of an H9N2 avian influenza virus, and all gene fragments in a recombinant virus come from the avian influenza virus, so that higher safety is achieved. The recombinant H5N1 avian influenza virus can be subcultured on the MDCK cell to obtain a strain with high proliferation titer, so that the problem of the lack of a large quantity of chicken embryos during explosion of avian influenza is solved.
