  1. 16. Optical Properties of Single Silicon Quantum Dots

    Författare :Federico Pevere; Jan Linnros; Uwe Kortshagen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silicon; nanocrystals; quantum dots; photoluminescence; optics; emission; absorption; Fysik; Physics;

    Sammanfattning : For over 60 years silicon (Si) has dominated the semiconductor microelectronics industry mainly due to its abundance and good electrical and material properties. The advanced processing technology of Si has made it the workhorse for photovoltaics industry as well. LÄS MER

  3. 17. Optical Properties of Nanoparticles in Composite Materials

    Författare :Lin Dong; Sergei Popov; Ari Friberg; Toralf Scharf; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields. LÄS MER

  4. 18. Planning and Provisioning Strategies for Optical Core Networks

    Författare :Ajmal Muhammad; Robert Forchheimer; Lena Wosinska; Massimo Tornatore; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Optical communication networks are considered the main catalyst for the transformation of communication technology, and serve as the backbone of today's Internet. The inclusion of exciting technologies, such as, optical amplifiers, wavelength division multiplexing (WDM), and reconfigurable optical add/drop multiplexers (ROADM) in optical networks have made the cost of information transmission around the world negligible.

  5. 19. Electron Transport and Optical Properties in Mesoscopic Systems

    Författare :Anna Grincwajg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main subject of this Thesis is optical properties of quantum point contact systems and their influence on the electron transport. A quantum point contact is a narrow constriction in a two-dimensional electron gas, where the width of the constriction can be controlled by means of a gate voltage. LÄS MER

  7. 20. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization

    Författare :Svante Nordlander; Högskolan Dalarna; []
    Nyckelord :Solar Combisystems Concentrating Collector Optimization Incidence Angle Optical Efficiency Simulation TRNSYS Stagnation;

    Sammanfattning : In a northern European climate a typical solar combisystem for a single family house normally saves between 10 and 30 % of the auxiliary energy needed for space heating and domestic water heating. It is considered uneconomical to dimension systems for higher energy savings. Overheating problems may also occur. LÄS MER
