  1. 6. Towards Novel AlGaN-Based Light Emitters

    Författare :Martin Stattin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlGaN; light emitting diode; deep ultraviolet; III-Nitrides; near infrared; quantum cascade laser;

    Sammanfattning : The unique properties of the AlGaN semiconductors make them a suitable choice for optoelectronic devices at both short and long wavelengths, based on interband and intersubband transitions, respectively. What sets AlGaN apart from other wide-bandgap semiconductors is the possibility to obtain both p- and n-type conductivity as well as the direct bandgap. LÄS MER

  3. 7. Organic electronic switch devices

    Författare :Fredrik Jakobsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER

  5. 9. Towards flexible organic electronics : photoelectron spectroscopy of surfaces and interfaces

    Författare :Stina Jönsson; Ian D. Parker; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Intensive studies of conjugated molecules and polymers are carried out all over the world with the intent of obtaining cheap and efficient organic electronic devices. The most mature application at the moment is the light-emitting diode, but also photovoltaic cells and different types of transistors shows promising results. LÄS MER

  7. 10. Heterojunctions between zinc oxide nanostructures and organic semiconductor

    Författare :Amal Hansson (f.d. Wadeasa); Xavier Crispin; Dominique Vuillaume; Linköpings universitet; []
    Nyckelord :ZnO nanostructures; Organic semiconductors; LEDs; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Lighting is a big business, lighting consumes considerable amount of the electricity. These facts motivate for the search of new illumination technologies that are efficient. Semiconductor light emitting diodes (LEDs) have huge potential to replace the traditional primary incandescent lighting sources. LÄS MER
