  2. 11. Nanoscale Crystal Growth: The Importance of Interfaces and Phase Boundaries Kristallväxt på Nanometer Skala: Vikten av Ytor och Gränser

    Author : Brent Wacaser; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kristallografi; fasjämvikt; Semiconductory physics; Halvledarfysik; thermal and mechanical properties; crystallography; phase equilibria; Kondenserade materiens egenskaper:struktur; egenskaper termiska och mekaniska ; Condensed matter:stucture; Fysik; Physics; epitaxy; VLS; MOVPE; CBE; nanostructures; crystal growth; nanowires; III-V semiconductors; growth mechanism; MBE; Material technology; Materiallära; materialteknik;

    Abstract : Surfaces and interfaces have a special significance to nanotechnology because the surface/volume ratio of nanomaterials is larger than for bulk materials. Therefore, interfaces of nanomaterials are usually more important to the properties of nanomaterials than for larger scale materials. READ MORE

  4. 12. Vertical III-V/High-k Nanowire MOS Capacitors and Transistors

    Author : Jun Wu; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; MOS capacitor; C-V; XPS; MOVPE; InGaAs; InAs; High-k; RF; Track-and-hold circuit;

    Abstract : The emerging nanowire technology in recent years has attracted an increasing interest for high-speed, low-power electronics due to the possibility of a gate-all-around (GAA) geometry enabling aggressive gate length scaling, together with the ease in incorporating high-mobility narrow band gap III-V semiconductors such as InAs on Si substrates. These benefits make vertical nanowire transistors an attractive alternative to the planar devices. READ MORE
