    摘要: A wafer suitable for epitaxial growth of gallium nitride (GaN) in a Metal Oxide Chemical Vapor Deposition (MOCVD) process. The wafer includes a silicon substrate having a front side and a back side and an edge extending between the front side and the back side, the edge including a front bevel surface connected to the front side and a back bevel surface connected to the back side, wherein the silicon substrate comprises an oxygen denuded silicon layer surrounding a core. The wafer further includes a protection layer being a thermally grown silicon oxide (SiO2) layer substantially covering the front bevel surface and the back bevel surface of the edge, while leaving at least a central region of the front side of the silicon substrate exposed, for preventing meltback during the MOCVD process.

    摘要: The invention relates to a method or an arrangement for the clock synchronization of a plurality of distributed modules of an information or communication system, said modules being coupled via a packet-switched network. At least two of said modules are controlled by a local clock generator of the modules using an adjustable frequency, and a clock signal is transmitted via the network in the form of clock signal packets in a synchronous minter with respect to the local clock of the modules. One of said at least two modules takes over the function of a master module, and all remaining said at least two modules, the slave module(s), synchronize the local clock of the modules with the clock of the master module, wherein said slave modules ascertain a measurement for the deviation of the local clock generator of the modules relative to the clock generator of the master module by comparing the clock signal transmitted by the master module with the clock signal of the modules and use said measurement in order to regulate the local clock generator of the modules.

    摘要: An ethylene homo- or copolymer composition is stabilized by suitable stabilizers conferring improved resistance against thermo-oxidative degradation, which occurs in the presence of liquid fuels comprising biodiesel, such as vegetable oil esters, in combination with oxygen. The stabilizers comprise a combination of at least two sterically hindered amine compounds or N-hydroxy- or N-oxylderivatives thereof in an amount of from 100 to 10 000 ppm. Such ethylene homo- or copolymer composition is highly suitable for articles of plastic and components for the transport and storage of liquid fuels comprising biodiesel, such as vegetable oil esters, preferably for plastic fuel tanks for automotive vehicles.
