  2. 21. Excitonic effects in ZnO

    Author : Shula Chen; Irina Buyanova; Weimin Chen; Ivan Ivanov; Linköpings universitet; []
    Keywords : ;

    Abstract : Zinc Oxide (ZnO) is an extensively researched II-VI wide bandgap semiconductor material. As a promising material for future optoelectronic and spintronic applications, it continues to attract enormous amount of interest. READ MORE

  4. 22. LIPASES AND PHOSPHOLIPASES IN PHOSPHOLIPID SYNTHESIS

    Author : Carmen Virto; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transphosphatidylation; acylation; vinyl ester; Phospholipid synthesis; lysophospholipid; kinetics; Biotechnology; Bioteknik;

    Abstract : The synthesis of phospholipids with defined fatty acid and polar head composition catalysed by lipases and phospholipases was investigated. Lipases from Rhizopus arrhizus and Candida antarctica were used for the direct acylation of DL-a-glycerophosphate and L-a-glycerophosphatidylcholine, with different fatty acids. READ MORE

  5. 23. Fabrication and Characterization of ZnO Nanorods Based Intrinsic White Light Emitting Diodes (LEDs)

    Author : Nargis Bano; Omer Nour; Magnus Willander; David Rogers; Linköpings universitet; []
    Keywords : Zinc Oxide nanorods; White light emitting diode; Photoluminescence; Cathodoluminescence; Electroluminescence; Deep level transient spectroscopy DLTS ;

    Abstract : ZnO material based hetero-junctions are a potential candidate for the design andrealization of intrinsic white light emitting devices (WLEDs) due to several advantages overthe nitride based material system. During the last few years the lack of a reliable andreproducible p-type doping in ZnO material with sufficiently high conductivity and carrierconcentration has initiated an alternative approach to grow n-ZnO nanorods (NRs) on other ptypeinorganic and organic substrates.

  6. 24. Electrically active defects in 4H silicon carbide

    Author : Liutauras Storasta; Tsunenobu Kimoto; Linköpings universitet; []
    Keywords : ;

    Abstract : Development of future technology needs to widen the application areas of semiconductor devices. The increased requirements are beyond the limits of the most common semiconductors today like silicon or gallium arsenide. Use of new materials could resolve many performance issues and also offer increased reliability and reduced cost of the devices. READ MORE
