1. Scanning capacitance microscopy for semiconductor characterisation
Sammanfattning : .... LÄS MER
2. Characterisation of the Specific Capacitance of Superconducting Tunnel Junctions
Sammanfattning : Superconductor-Insulator-Superconductor (SIS) tunnel junctions are widely used as the mixing component in mm and sub-mm receivers for radio astronomy and environmental science. SIS mixers offer superior noise performance close to the quantum limit for frequencies up to 1 THz. LÄS MER
3. Novel Processing and Electrical Characterization of Nanowires
Sammanfattning : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. LÄS MER
4. Affinity biosensors based on a capacitive transducer
Sammanfattning : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. LÄS MER
5. Protein-based capacitive biosensors for the detection of heavy-metal ions
Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER
