1. 21. Integration of silicide nanowires as Schottky barrier source/drain in FinFETs

   Författare :Zhen Zhang; Shi-Li Zhang; Tsu-Jae King Liu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS technology; MOSFET; FinFET; Schottky diode; Schottky barrier soure drain; silicide; SALICIDE; SOI; multiple-gate; nanowire; sidewall transfer lithography; Electronics; Elektronik;

   Sammanfattning : The steady and aggressive downscaling of the physical dimensions of the conventional metal-oxide-semiconductor field-effect-transistor (MOSFET) has been the main driving force for the IC industry and information technology over the past decades. As the device dimensions approach the fundamental limits, novel double/trigate device architecture such as FinFET is needed to guarantee the ultimate downscaling. LÄS MER

3. 22. High Quality III-V Semiconductors/Si Heterostructures for Photonic Integration and Photovoltaic Applications

   Sammanfattning : This thesis deals with one of the promising strategies to monolithically integrate III-V semiconductors with silicon via epitaxial lateral overgrowth (ELOG) technology and is supported by extensive experimental results. The aimed applications are light sources on silicon for electronics-photonics integration and cost effective high efficiency multijunction solar cells. LÄS MER

4. 23. Ceria-based nanocomposite electrolyte for low-temperature solid oxide fuel cells

   Författare :Ying Ma; Mamoun Muhammed; Peter Lund; KTH; []
   Nyckelord :;

   Sammanfattning : Solid oxide fuel cells (SOFCs) have attracted much attention because of their potential of providing an efficient, environmentally benign, and fuel-flexible power generation system for both small power units and for large scale power plants. However, conventional SOFCs with yttria-stabilized zirconia (YSZ) electrolyte require high operation temperature (800-1000°C), which presents material degradation problems, as well as other technological complications and economic obstacles.

   Författare :Reza Sanatinia; Anand Srinivasan; Andrea Fiore; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopillar; nanowires; nanophotonics; nanofabrication; III-V semiconductors; photovoltaics; second-harmonic generation; top-down approach; colloidal lithography; antireflection; modal dispersion; polarization; nanowaveguide; indium phosphide; gallium arsenide; gallium phosphide; Physics; Fysik;

   Sammanfattning : Optical properties of semiconductor nanowires (NWs)/nanopillars (NPs), as individual or ensemble, have attracted significant research interest in recent years. Their potential applications range from solid-state lighting, photovoltaics, lasing and nonlinear optics to sensing and life sciences. LÄS MER

7. 25. Semantic mapping using virtual sensors and fusion of aerial images with sensor data from a ground vehicle

   Författare :Martin Persson; Achim Lilienthal; Javier González; Örebro universitet; []
   Nyckelord :semantic mapping; aerial image; mobile robot; supervised learning; semi-supervised learning; TECHNOLOGY; TEKNIKVETENSKAP; Industriell mätteknik; Industrial Measurement Technology;

   Sammanfattning : In this thesis, semantic mapping is understood to be the process of putting a tag or label on objects or regions in a map. This label should be interpretable by and have a meaning for a human. The use of semantic information has several application areas in mobile robotics. LÄS MER
