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

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

    Sammanfattning : 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.

  7. 10. Graphene-based nanocomposites for electronics and photocatalysis

    Författare :Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nour; Maria Messing; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Zinc oxide; Silver iodine; Plasmonics; Nanocomposites; Conjugated electronics; Photocatalysis; Photodegradation;

    Sammanfattning : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.
