1. 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
2. Computer Simulations of Photonic Semiconductor Devices
Sammanfattning : This thesis aims to provide insight into three important aspects of modern computer simulation techniques related to advanced photonic semiconductor devices. These aspects are quantum size effects, waveguiding properties, and device dynamics. LÄS MER
3. Physics of palladium metal-oxide-semiconductor devices
Sammanfattning : This thesis Palladium gate metal-oxide-semiconductor (PdMOS) devices are used as hydrogen sensors. It is shown that the sensitivity is only partly due to the change of the effective work function of the Pd gate on hydrogen adsorption. Sodium ion drift experiments have shown that hydrogen-sodium interactions occur in PdMOS devices. LÄS MER
4. Advanced TCAD Simulations and Characterization of Semiconductor Devices
Sammanfattning : Today, micro- and nano-electronic devices are becoming more complex and advanced as the dimensions are shrinking. It is therefore a very challenging task to develop new device technologies with performance that can be predicted. LÄS MER
5. Gas sensitivity of modified metal-oxide-semiconductor devices
Sammanfattning : Gas sensitive thin metal-oxide-semiconductor (MOS) structures have been used to study the effect of different modifications of the gate metal. In order to increase the selectivity of the gas sensor photoresist was used as a gas permeable membrane. LÄS MER
