   Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER

3. 2. Silicon nanowires, nanopillars and quantum dots : Fabrication and characterization

   Författare :Robert Juhasz; Jan Linnros; Philippe M. Fauchet; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon nanowires; silicon nanopillars; silicon quantum dots; size-reduction; thermal oxidation; electrochemical etching of silicon; photoluminescence; Semiconductor physics; Halvledarfysik;

   Sammanfattning : Semiconductor nanotechnology is today a very well studied subject, and demonstrations of possible applications and concepts are abundant. However, well-controlled mass-fabrication on the nanoscale is still a great challenge, and the lack of nanofabrication methods that provide the combination of required fabrication precision and high throughput, limits the large-scale use of nanodevices.

4. 3. Fabrication and characterization of single luminescing quantum dots from 1D silicon nanostructures

   Författare :Benjamin Bruhn; Jan Linnros; Luca Dal Negro; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silicon; quantum dot; nanocrystal; nanowire; nanostructure; photoluminescence;

   Sammanfattning : Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter. LÄS MER

5. 4. Silicon Nanowire Based Sensors for Bacterial Tests

   Författare :Yingtao Yu; Zhen Zhang; Mihai Adrian Ionescu; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nanowire; field-effect transistor; antibiotic susceptibility test; bacterial metabolism; nanoelectromechanical sensor; multiplexed detection;

   Sammanfattning : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. LÄS MER

7. 5. Schottky Contacs on Silicon Nanowires

   Författare :Johan Piscator; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Silicon On Insulator SOI ; Schottky contacts; Palladium silicide; Silicon nanowire;

   Sammanfattning : This thesis demonstrates the effect of charge on Schottky barrier height for metal contacts at the end surfaces of silicon nanowires. It is shown, by measurements and analytical models, how the effective electron barrier is lowered by a positive charge introduced into an oxide embedding the wire. LÄS MER
