  1. 1. Silicon nanowires, nanopillars and quantum dots Fabrication and characterization

    University dissertation from Stockholm : KTH

    Author : Robert Juhasz; Jan Linnros; Philippe M. Fauchet; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon nanowires; silicon nanopillars; silicon quantum dots; size-reduction; thermal oxidation; electrochemical etching of silicon; photoluminescence; NATURAL SCIENCES Physics Condensed matter physics Semiconductor physics; NATURVETENSKAP Fysik Kondenserade materiens fysik Halvledarfysik;

    Abstract : 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.

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

    University dissertation from Stockholm : KTH

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

    Abstract : 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. READ MORE

  3. 3. Schottky Contacs on Silicon Nanowires

    University dissertation from Stockholm : KTH

    Author : Johan Piscator; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Silicon On Insulator SOI ; Schottky contacts; Palladium silicide; Silicon nanowire;

    Abstract : 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. READ MORE

  4. 4. Silicon Nanowire Field-Effect Devices as Low-Noise Sensors

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Xi Chen; Zhen Zhang; Shi-Li Zhang; Si Chen; Fengnian Xia; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nanowire; field-effect transistor; Schottky junction gate; low frequency noise; ion sensor; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : 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. READ MORE

  5. 5. Design, Fabrication, and Characterization of Nano-Photonic Components Based on Silicon and Plasmonic Material

    University dissertation from Stockholm : KTH

    Author : Liu Liu; Lars Thylén; Roe Baets; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nano-photonics; finite-difference time-domain method; finite-difference mode solver; amorphous silicon; silicon nanowire; arrayed waveguide grating; photonic crystal; TECHNOLOGY Electrical engineering; electronics and photonics Photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Fotonik;

    Abstract : Size reduction is a key issue in the development of contemporary integrated photonics. This thesis is mainly devoted to study some integrated photonic components in sub-wavelength or nanometric scales, both theoretically and experimentally. READ MORE
