  1. 21. Integration of Ferroelectric HfO2 onto a III-V Nanowire Platform

    Författare :Anton E. O. Persson; Nanoelektronik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferroelectricity; ferroelectric FET; ferroelectric tunnel junction; tunnel field effect transistors; HZO; III-V; nanowire;

    Sammanfattning : The discovery of ferroelectricity in CMOS-compatible oxides, such as doped hafnium oxide, has opened new possibilities for electronics by reviving the use of ferroelectric implementations on modern technology platforms. This thesis presents the ground-up integration of ferroelectric HfO2 on a thermally sensitive III-V nanowire platform leading to the successful implementation of ferroelectric transistors (FeFETs), tunnel junctions (FTJs), and varactors for mm-wave applications.

  3. 22. Transport in nanowire-based quantum dot systems: Heating electrons and confining holes

    Författare :Sven Dorsch; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Quantum dot; double quantum dot; Thermoelectric effect; Phonon-assisted transport; GaSb; g-factor; Fysicumarkivet A:2022:Dorsch;

    Sammanfattning : Quantum dots embedded in an electronic circuit allow precise control over the charge transport behaviour of the system: Charge carriers can be individually trapped or precisely shuffled between a series of quantum dots in a strictly sequential manner. This introduces ideal conditions to study fundamental quantum physics and such devices are in the focus of extensive efforts to develop quantum information related applications. LÄS MER

  7. 25. Silicon Nanowire Based Sensors for Bacterial Tests

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

    Sammanfattning : 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. LÄS MER
