    摘要: A process is provided for fabricating a semiconductor device having a germanium nanofilm layer that is selectively deposited on a silicon substrate in discrete regions or patterns. A semiconductor device is also provided having a germanium film layer that is disposed in desired regions or having desired patterns that can be prepared in the absence of etching and patterning the germanium film layer. A process is also provided for preparing a semiconductor device having a silicon substrate having one conductivity type and a germanium nanofilm layer of a different conductivity type. Semiconductor devices are provided having selectively grown germanium nanofilm layer, such as diodes including light emitting diodes, photodetectors, and like. The method can also be used to make advanced semiconductor devices such as CMOS devices, MOSFET devices, and the like.

    摘要: A nuclear radiation detection system using narrowband UV crystal filters is disclosed. Since the photons produced during the decay of β- and γ-radiation can be detected in the spectral range of about 200-350 nm (the ultraviolet range), UV filter based photo sensors are utilized for detection. The nuclear radiation detection system comprises an optical assembly capable of focusing on a source of radiation, a UV filter assembly having a narrowband UV crystal filter and positioned to receive light transmitted through the optical assembly, and a light detector positioned to receive light transmitted through the UV filter assembly. The narrowband UV crystal filter is fabricated from crystals selected from the group consisting of nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate. The nickel fluorosilicate, nickel fluoroborate, and potassium nickel sulfate may be doped to achieve even narrower band filter. The radiation detection system can be used to monitor contamination in a nuclear plant or a nuclear waste dump site. It may also be used for surveillance of contamination in case of a nuclear accident.

    摘要: An apparatus, system, and method quickly backs up data in an emergency situation and reduces battery backup dependence. The apparatus may include a backup module and a dedicated computer readable storage device. The backup module interfaces with system memory and selectively transmits modified data to the storage device in response to a detected system failure. The dedicated storage device stores the modified data around the outer edge of a hard disk in order to increase write performance. The system may include the backup module, the storage device, a plurality of client devices, and a plurality of storage devices. The method includes storing modified and unmodified data, detecting a system failure, and transmitting modified data stored in a memory module to a dedicated computer readable backup device. Upon rebooting the device, the method may include restoring the modified data to the system memory and destaging the modified data to the plurality of storage devices.
