3. Vertical III-V Nanowire Transistors for Low-Power Electronics
Sammanfattning : Power dissipation has been the major challenge in the downscaling of transistor technology. Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) have struggled to keep a low power consumption while still maintaining a high performance due to the low carrier mobilities of Si but also due to their inherent minimum inverse subthreshold slope (S ≥ 60 mV/dec) which is limited by thermionic emission.

4. 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
