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

17. Vertical III-V Semiconductor Devices
Sammanfattning : 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. LÄS MER
18. Nanophotonics in absorbing III-V nanowire arrays

19. Photoelectron Spectroscopy Studies of III-V Semiconductor Systems
Sammanfattning : Photoelectron spectroscopy has been used as a main tool to study a number of III-V semiconductor surfaces. This thesis includes studies of a surface reaction, As/InP(110), thin heteroepitaxial layers, InAs on GaAs(111)A and GaAs on AlAs(100), and a diluted magnetic semiconductor, Ga1-xMnxAs. LÄS MER
20. Vertical III-V Nanowires For In-Memory Computing
Sammanfattning : In recent times, deep neural networks (DNNs) have demonstrated great potential in various machine learning applications,such as image classification and object detection for autonomous driving. However, increasing the accuracy of DNNsrequires scaled, faster, and more energy-efficient hardware, which is limited by the von Neumann architecture whereseparate memory and computing units lead to a bottleneck in performance.
