  2. 1. Microstructural Development of Nanocrystalline Ni- and Co-Based Materilas upon Annealing

    Author : Melina da Silva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ni; grain growth; nanocrystalline materials; Co-P; Ni-Fe; thermal stability; TEM in-situ annealing;

    Abstract : Nanocrystalline materials are a relatively new group of materials that are constituted by crystals/grains of a few nanometers in size. Because their mechanical, physical and chemical properties are often superior compared to their microcrystalline counterparts, these materials are attractive for many industrial applications.

  4. 2. Infrared Photodetectors based on InSb and InAs Nanostructures via Heterogeneous Integration-Rapid Melt Growth and Template Assisted Selective Epitaxy

    Author : Heera Menon; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rapid Melt Growth RMG ; Template Assisted Selective Epitaxy TASE ; InSb; InAs; infrared detectors; nBn detector; photoconductor; nanostructures; nanowires;

    Abstract : Monolithic heterogeneous integration of III-V semiconductors with the contemporary Si Complementary Metal Oxide Semiconductor (CMOS) technology has instigated a wide range of possibilities and functionalities in the semiconductor industry, in the field of digital circuits, optical sensors, light emitters, and high-frequency communication devices. However, the integration of III-V semiconductors is not trivial due to the differences in lattice parameters, polarity, and thermal expansion coefficient. READ MORE

  5. 3. 40Ar/39Ar, AFT and (U-Th)/He thermochronologic implications for the low-temperature geological evolution in SE Sweden

    Author : Pia Söderlund; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 40Ar-39Ar; Fennoscandian Shield; U-Th He; AFT; geochronology; thermochronology; cooling; uplift;

    Abstract : The Oskarshamn and Forsmark areas in the Fennoscandian Shield, SE Sweden, have been chosen as potential sites for hosting highly radioactive nuclear waste. To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c.

  6. 4. Detection and removal of traps at the SiO2/SiC interface

    Author : Halldor Olafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface states; thermally stimulated current TSC ; positron annihilation spectroscopy PAS ; silicon carbide SiC ; metal-oxide-semiconductor field-effect transistor MOSFET ; transmission electron microscopy TEM ; deep level transient spectroscopy DLTS ; metal-oxide-semiconductor MOS ; field-effect mobility; capacitance-voltage C-V ;

    Abstract : The interface between silicon dioxide (SiO2) and silicon carbide (SiC) is at the heart of the SiC metal-oxide-semiconductor field-effect (MOSFET) transistor. The technology to produce a high quality SiO2/SiC interface does not exist today, hampering further development of the SiC MOSFET. READ MORE

  7. 5. Complex Oxide Photonic Crystals

    Author : Dzmitry Dzibrou; Alex Grishin; Peter Lazor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; magneto-optical effects; refractive index; iron garnet; Optics; Optik;

    Abstract : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. READ MORE
