1. Electronic Sensors Based on Nanostructured Field-Effect Devices
Sammanfattning : Point-of-care (POC) diagnostics presents a giant market opportunity with profound societal impact. In particular, specific detection of DNA and protein markers can be essential for early diagnosis of e.g. cancer, cardiovascular disease, infections or allergies. LÄS MER
2. Graphene field-effect transistors and devices for advanced high-frequency applications
Sammanfattning : New device technologies and materials are continuously investigated, in order to increase the bandwidth of high-speed electronics, thereby extending data rate and range of applications. The 2D-material graphene, with its intrinsically extremely high charge carrier velocity, is considered as a promising new channel material for advanced high frequency field-effect transistors.

3. Silicon Nanowire Field-Effect Devices as Low-Noise Sensors
Sammanfattning : In the past decades, silicon nanowire field-effect transistors (SiNWFETs) have been explored for label-free, highly sensitive, and real-time detections of chemical and biological species. The SiNWFETs are anticipated for sensing analyte at ultralow concentrations, even at single-molecule level, owing to their significantly improved charge sensitivity over large-area FETs. LÄS MER
4. Heterostructure Field Effect Transistors and Millimeter Wave Integrated Circuits
Sammanfattning : This thesis deals with the research and development of HFETs and HFET based circuits. One of the main aims of the work presented in this thesis has been to develop processes to fabricate state of the art devices and circuits. LÄS MER
5. Effects of impurities on charge transport in graphene field-effect transistors
Sammanfattning : In order to push the upper frequency limit of high speed electronics further, thereby extending the range of applications, new device technologies and materials are continuously investigated. The 2D material graphene, with its intrinsically extremely high room temperature charge carrier velocity, is regarded as a promising candidate to push the frequency limit even further. LÄS MER
