Aligned AlN nanorods with multi-tipped surfaces - Growth, field-emission, and cathodoluminescence properties

Well-aligned aluminum nitride nanorods with hairy surfaces (see Figure) are a new hierarchical nanostructure with emission-properties. promising field The columnar nanostructures are produced by a vapor-solid process. Their cathodoluminescence spectrum reveals an intense emission peak with a low turn-on field of 3.8 V mu m(-1) gesting potential applications in optoelectronic nanodevices.
