1. 1. Silicon Nanoribbon FET Sensors : Fabrication, Surface Modification and Microfluidic Integration

   Författare :Roodabeh Afrasiabi; Jan Linnros; Michel Calame; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Over the past decade, the field of medical diagnostics has seen an incredible amount of research towards the integration of one-dimensional nanostructures such as carbon nanotubes, metallic and semiconducting nanowires and nanoribbons for a variety of bio-applications. Among the mentioned one-dimensional structures, silicon nanoribbon (SiNR) field-effect transistors (FET) as electro-chemical nanosensors hold particular promise for label-free, real-time and sensitive detection of biomolecules using affinity-based detection.

3. 2. Electron microscopy of ion implanted silicon carbide

   Författare :Per Persson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis investigates structural defects into Silicon Carbide (SiC) in processed Al and B ion implantated samples. Ion implantation is currently the preferred way to introduce impurity atoms into the SiC crystal lattice. The structural defects found was concluded to be extrinsic dislocation loops composed of excess Si interstitials. LÄS MER

4. 3. Electrically active defects in 4H silicon carbide

   Författare :Liutauras Storasta; Tsunenobu Kimoto; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Development of future technology needs to widen the application areas of semiconductor devices. The increased requirements are beyond the limits of the most common semiconductors today like silicon or gallium arsenide. Use of new materials could resolve many performance issues and also offer increased reliability and reduced cost of the devices. LÄS MER

5. 4. Simulations of Silicon Carbide Chemical Vapor Deposition

   Författare :Örjan Danielsson; Erik Janzén; Anne Henry; Michel Pons; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. LÄS MER

7. 5. Structural investigation and lateral growth of silicon carbide crystals

   Författare :Henrik Jacobson; Marek Skowronski; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Today, most of the electronic device technology is based on Si as a semiconducting material. The demands from the industry of improved performance within smaller devices drives the silicon based devices to the limits imposed by nature and not by technology. To realize these demands new materials like silicon carbide (SiC) must be investigated. LÄS MER
