  1. 6. Application of SiGe(C) in high performance MOSFETs and infrared detectors

    Författare :Mohammadreza Kolahdouz Esfahani; Henry Radamson; Ya-Hong Xie; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Germanium Carbon SiGeC ; Reduced Pressure Chemical Vapor Deposition RPCVD ; Epitaxy; Pattern Dependency; MOSFET; Mobility; bolometer; Quantum Well; Infrared IR Detection; Ni Silicide; High Resolution X-ray Diffraction HRXRD ; High Resolution Scanning Electron Microscopy HRSEM ; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Epitaxially grown SiGe(C) materials have a great importance for many device applications. In these applications, (strained or relaxed) SiGe(C) layers are grown either selectively on the active areas, or on the entire wafer. LÄS MER

  3. 7. Gamma-ray Spectroscopy ofNeutron-rich 111 Mo, 85,87 Ge andSelf-Conjugate 88 Ru Far From Stability

    Författare :Özge Aktas; Ayse Nyberg; Bo Cederwall; Augusto Machiavelli; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Sammanfattning : The neutron-deficient self-conjugate (N=Z) nucleus 8844 Ru 44 was populatedvia the heavy ion fusion evaporation reaction 54 Fe( 36 Ar, 2n) 88 Ru in an ex-periment performed at the GANIL accelerator laboratory in France. Usingthe AGATA γ-ray spectrometer together with ancillary detectors, promptγ − γ − 2n coincidence and charge particle anticoincidence analysis was per-formed for the low-lying energy spectrum of 88 Ru.

  4. 8. Some studies in nuclear structure by coincidence measurements

    Författare :Benny Sundström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The coincidence technique is a basic method for determining nuclear parameters.From single and coincidence gamma-ray measurements, using high resolution Ge(Li) detectors, a level scheme of 123Sb was determined. LÄS MER

  5. 9. Optical characterization of Silicon-based self-assembled nanostructures

    Författare :Bouchaib Adnane; Wei-Xin Ni; Per Olof Holtz; Göran Hansson; Susumo Fukatsu; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This PhD thesis summarizes the work carried on the optical characterizations of some Si-based self-assembled nanostructures, particularly SiGe/Si quantum dots (QDs) and nanocrystalline (nc)-Si embedded in mesoporous silica (MS) using photoconductivity (PC), photoluminescence (PL), and photoluminescence excitation (PLE) measurements. The spectroscopic studies of SiGe/Si QDs grown on Si by molecular beam epitaxy revealed for the first time well-resolved PLE resonances. LÄS MER

  7. 10. FPGA-based Instrumentation for Advanced Physics Experiments

    Författare :Attila Hidvégi; Samuel Silverstein; Martin Grossmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; Data acquisition; clock distribution; trigger; FPGA; PCB; LHC; ATLAS; XFEL; fysik; Physics;

    Sammanfattning : Modern physical experiments often demand advanced instrumentation based on advances in  technology. This work describes four instrumentation physics projects that are based on modern, high-capacity Field-Programmable Gate Arrays, making use of their versatility, programmability, high bandwidth communication interfaces and signal processing capabilities.
