1. 11. Application of Vibrational Spectroscopy in Organic Electronics

   Författare :Mohammad Javad Jafari; Thomas Ederth; Isak Engquist; Annemarie Pucci; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The rapid technological developments enforce us to live in an increasingly electronic world, and the revolutionary usage of conjugated polymers in electronics in the late 1970s accelerated these developments, based on the unique characteristics of conjugated polymers, such as low cost, easy processing, mechanical flexibility, large-area application and compatibility with a variety of substrates. Organic electronic devices are commercially available in the form of, for example, solar cells, transistors, and organic light-emitting diode (OLED) displays. LÄS MER

3. 12. Monopolar and Bipolar Membranes in Organic Bioelectronic Devices

   Författare :Erik O. Gabrielsson; Magnus Berggren; Edwin Jager; Daniel Simon; Ari Ivaska; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioelectronics; ionic; ion transport; bipolar membrane; conjugated polymer; amyloid; self-assembly;

   Sammanfattning : In the 1970s it was discovered that organic polymers, a class of materials otherwise best know as insulating plastics, could be made electronically conductive. As an alternative to silicon semiconductors, organic polymers offer many novel features, characteristics, and opportunities, such as producing electronics at low costs using printing techniques, using organic chemistry to tune optical and electronic properties, and mechanical flexibility.

4. 13. Studies of cosmic rays with the anticoincidence system of the PAMELA satellite experiment

   Författare :Silvio Orsi; Mark Pearce; Martin Pohl; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrophysics; astroparticle physics; antimatter; organic scintillators; cosmic rays; trapped particles; Astroparticle physics; Astropartikelfysik;

   Sammanfattning : PAMELA is a satellite-borne experiment designed to study the charged component of the cosmic radiation of galactic, solar and trapped nature. The main scientific objective is the study of the antimatter component of cosmic rays over a wide range of energies (antiprotons: 80 MeV–190 GeV, positrons: 50 MeV–270 GeV). LÄS MER

5. 14. Luminescent Polymer Films in Layered Devices : A Theoretical and Experimental Study on Light Emission from Polymer-based Devices

   Författare :Thomas Granlund; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis concerns optical modelling and characterisation of thin film layered structures, including luminescent conjugated polymers, with respect to the emission properties. Included in the study were three different types of devices: Organic light-emitting diodes, microcavities and half cavities. LÄS MER

7. 15. Photoluminescence Characteristics of III-Nitride Quantum Dots and Films

   Författare :Martin Eriksson; Per-Olof Holtz; Peder Bergman; Fredrik Karlsson; Volodymyr Khranovskyy; Yasuhiko Arakawa; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : III-Nitride semiconductors are very promising in both electronics and optical devices. The ability of the III-Nitride semiconductors as light emitters to span the electromagnetic spectrum from deep ultraviolet light, through the entire visible region, and into the infrared part of the spectrum, is a very important feature, making this material very important in the field of light emitting devices.
