  1. 11. Flashlamp Annealing for Improved Ferroelectric Junctions

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Theodor Blom; [2023]
    Nyckelord :Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Sammanfattning : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. LÄS MER

  3. 12. High Level Synthesis for ASIC and FPGA

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Malin Heyden; [2023]
    Nyckelord :HLS; high level synthesis; asic; fpga; catapult; filter; sfir; Technology and Engineering;

    Sammanfattning : This thesis aims to evaluate the performance of Siemens’ High Level Synthesis (HLS) tool Catapult. HLS can be considered the next step up in abstraction level from writing traditional Register Transfer Level (RTL) code which is time consuming and error prone. LÄS MER

  4. 13. Numerical study of a jet impacting a heated object

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Moutaz Hammoud; [2023]
    Nyckelord :Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER

  5. 14. Investigation of switching power losses of SiC MOSFET : used in a DC/DC Buck converter

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :André Xavier Svensson; [2022]
    Nyckelord :Switching power losses; Metal Oxide Semiconductor Field Effect Transistor; Silicon carbide; Synchronous Buck converter; Wide Band Gap; Double Pulse Test; Efficiency; Temperature; Växlande effektförluster; Fälteffekttransistor; Kiselkarbid; Synchronous Buck omvandlare; Wide Band Gap; Double Pulse Test; Verkningsgrad; Temperatur;

    Sammanfattning : All DC/DC converter products include power electronic circuits for power conversion.It is important to find an efficient way for power conversion to reduce power losses and reduce the need for cooling and achieve environmentally friendly solutions.The use of semiconductor switches of wide band gap type is a solution to the problem.

  7. 15. Investigation and evaluation of optical distance sensors

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Olof Wigzell; [2022]
    Nyckelord :optics; radiometry; senssor; microcontroller; irradiance; circuit design; calibration; validation;

    Sammanfattning : Optical sensors are among the sensors that are often used for distance measurements. An optical distance sensor is basically made of a light emitter (Tx) such as a light emitting diode (LED), a light receiver (Rx) such as a photosensitive transistor, and a circuit supporting the operation of the Tx and Rx.
