    Sammanfattning : Monolithic three-dimensional (M3D) integration, it has been proposed,can overcome the limitations of further circuits’ performance improvementand functionality expansion. The emergence of the internet of things (IoT) isdriving the semiconductor industry toward the fabrication of higher-performancecircuits with diverse functionality. LÄS MER

  3. 2. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration

    Författare :Konstantinos Garidis; Per-Erik Hellström; Mikael Östling; Sten Vollebregt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon; germanium; epitaxy; selective; pn junction; germanium on insulator; GOI; Ge PFET; bonding; monolithic; sequential; three dimensional; 3D; low temperature; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. LÄS MER

  4. 3. InP/GaInP Nanowires for Tandem Junction Solar Cells : Growth, Processing, and Characterization

    Författare :Xulu Zeng; Fasta tillståndets fysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanowires; GaInP; InP; tandem; tunnel diode; solar cell;

    Sammanfattning : Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. LÄS MER

  5. 4. Growth and Characterization of Core-Branch Nanowire Structures

    Författare :Kristi Adham; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates growth of III – V semiconductor nanowire (NW) arrays, in a core- branch architecture, with the aim to develop diffusion driven light emitting diodes (LED) on NWs. Diffusion driven LEDs are based on the concept of decoupling the active region from the p-n junction. LÄS MER

  7. 5. Applications of Artificial Microcavities in Wafer Bonded Silicon

    Författare :Zhaohua Xiao; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A novel sensor structure has been investigated and extensively studied. The device can be used as a pressure sensor, a voltage measuring device and as an optical modulator. The sensor was made using thermal bonding and micromachining techniques. LÄS MER
