  2. 16. Silicon Nanowire Based Sensors for Bacterial Tests

    Author : Yingtao Yu; Zhen Zhang; Mihai Adrian Ionescu; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nanowire; field-effect transistor; antibiotic susceptibility test; bacterial metabolism; nanoelectromechanical sensor; multiplexed detection;

    Abstract : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. READ MORE

  4. 17. Design and characterisation of terahertz Schottky diode harmonic mixers

    Author : Divya Jayasankar; RISE Research Institutes of Sweden; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Schottky diodes; Phase locking; Harmonic mixers; Heterodyne receivers; Terahertz electronics; Frequency stabilisation; Frequency converters;

    Abstract : Efficient, compact, and reliable terahertz frequency converters preferably operating at ambient temperature are crucial for stabilising far-infrared optical sources. This thesis focuses on the design and characterisation of terahertz Schottky diode harmonic mixers for frequency stabilisation of quantum-cascade lasers. READ MORE

  6. 19. Development of Zinc Oxide Piezoelectric Nanogenerators for Low Frequency Applications

    Author : Eiman Satti Nour; Omer Nour; Magnus Willander; Osama O. Awadelkarim; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Zinc oxide ZnO ; hydrothermal growth; piezoelectricity; nanowires NWs ; nanogenerator NG ; energy harvesting; wireless data transmission;

    Abstract : Energy harvesting using piezoelectric nanomaterials provides an opportunity for advancement towards self-powered systems. Self-powered systems are a new emerging technology, which allows the use of a system or a device that perform a function without the need for external power source like for example, a battery or any other type of source.

  7. 20. Dopant diffusion in Si and SiGe

    Author : Jens S. Christensen; KTH; []
    Keywords : condensed matter;

    Abstract : Dopant diffusion in semiconductors is an interestingphenomenon from both technological and scientific points ofview. Firstly, dopant diffusion is taking place during most ofthe steps in electronic device fabrication and, secondly,diffusion is related to fundamental properties of thesemiconductor, often controlled by intrinsic point defects:self-interstitials and vacancies.
