  1. 1. Silicon Carbide Microwave Devices

    University dissertation from Chalmers University of Technology

    Author : Joakim Eriksson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Silicon Carbide; wide band gap devices; MESFET; Schottky diode; SBD; microwave devices; physical simulations; high-power microwave devices; diode mixer; resistive mixer;

    Abstract : This work deals with silicon carbide (SiC) microwave devices. It treats two devices; the Schottky diode and the metal semiconductor field effect transistor (MESFET). Different MESFET materials, fabrication processes, theoretical models for physical simulation, and device models are presented. READ MORE

  2. 2. Vertical III-V Semiconductor Devices

    University dissertation from Chalmers University of Technology

    Author : Tomas Bryllert; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Halvledarfysik; Semiconductory physics; heterostructure barrier varactor frequency multiplier; field effect transistor; resonant tunneling; artificial molecule; terahertz; nanowire; Quantum dots;

    Abstract : This thesis is based on three projects that deal with vertical III-V semiconductor devices. The work spans over basic research as well as more applied aspects of III-V semiconductor technology. All projects have in common that they rely on advanced epitaxial growth to form the starting material for device fabrication. READ MORE

  3. 3. Discrete and Continuous Shape Writing for Text Entry and Control

    University dissertation from Institutionen för datavetenskap

    Author : Per Ola Kristensson; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Text entry; Command entry; Human-computer interaction; Input devices; Shorthand; Keyboard; Software keyboard; Pattern recognition; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi;

    Abstract : Mobile devices gain increasing computational power and storage capabilities, and there are already mobile phones that can show movies, act as digital music players and offer full-scale web browsing. The bottleneck for information flow is however limited by the inefficient communication channel between the user and the small device. READ MORE

  4. 4. Creating Digital Traces of Ideas Evaluation of Computer Input Methods in Creative and Non-Creative Drawing

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stanislaw Zabramski; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evaluation; user performance; input methods; mouse; stylus; touch; tracing; ideation; Människa-dator interaktion; Human-Computer Interaction;

    Abstract : Ideas are formed in a process of idea generation that includes creation, development, and communication of new ideas. Drawing has been used as a support for ideation for centuries. Today, computerized tools are commonly used for drawing. Such tools form a user interface between the human and the resulting drawing presented on the screen. READ MORE

  5. 5. On Radio Frequency Behavioral Modeling Measurement Techniques, Devices and Validation Aspects

    University dissertation from Stockholm : Skolan för elektro- och systemteknik, Kungliga Tekniska högskolan

    Author : Per Niklas Landin; Högskolan i Gävle.; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : Effektförstärkare för radiofrekvensapplikationer utgör fortfarande ett av de största problemen i trådlösa kommunikationssystem. Detta beror på att dessa förstärkare är ickelinjära, har låg energieffektivitet och ger mycket distortioner. Bättre verktyg för att förstå och korrigera dessa beteenden är nödvändiga. READ MORE
