Depth-resolved cathodoluminescence study of zinc oxide nanorods catalytically grown on p-type 4H-SiC

Linköping University Post Print Study of luminescent centers in ZnO nanorods catalytically grown on 4H-p-SiC

High quality ZnO nanorods (NRs) were grown by the vapour-liquid-solid (VLS) technique on 4H-p-SiC substrates. Heterojunction light emitting diodes (LEDs) were fabricated. Electrical characterisation including deep level transient spectroscopy (DLTS) complemented by photolumincence (PL) are used to characterize the heterojunction LEDs. On contrary to previously published results on n-ZnO thin fi...

Study of Radiative Defects Using Current-Voltage Characteristics in ZnO Rods Catalytically Grown on 4H-p-SiC

Luminescence Properties of ZnO Nanostructures and Their Implementation as White Light Emitting Diodes (LEDs)

In the past decade the global research interest in wide band gap semiconductors has been focused on zinc oxide (ZnO) due to its excellent and unique properties as a semiconductor material. The high electron mobility, high thermal conductivity, good transparency, wide and direct band gap (3.37 eV), large exciton binding energy (60 meV) at room temperature and easiness of growing it in the nanost...

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

ZnO material based hetero-junctions are a potential candidate for the design and realization of intrinsic white light emitting devices (WLEDs) due to several advantages over the nitride based material system. During the last few years the lack of a reliable and reproducible p-type doping in ZnO material with sufficiently high conductivity and carrier concentration has initiated an alternative a...

Luminescence from Zinc Oxide Nanostructures and Polymers and their Hybrid Devices

Zinc oxide (ZnO) is a strong luminescent material, as are several polymers. These two materials have distinct drawbacks and advantages, and they can be combined to form nanostructures with many important applications, e.g., large-area white lighting. This paper discusses the origin of visible emission centers in ZnO nanorods grown with different approaches. White light emitting diodes (LEDs) we...
