Abstract
The present invention relates to light emitting diodes, LEDs. In particular the invention relates to a LED comprising a nanowire as an active component. The nanostructured LED according to the embodiments of the invention comprises a substrate and at an upstanding nanowire protruding from the substrate. A pn-junction giving an active region to produce light is present within the structure. The nanowire, or at least a part of the nanowire, forms a wave-guiding section directing at least a portion of the light produced in the active region in a direction given by the nanowire.
Claims3
A method of fabricating a nanostructured LED, comprising first growing a nanowire over a substrate in a first growth mode promoting nanowire growth followed by selectively, epitaxially growing a semiconductor volume element on an upper portion of the nanowire in a second growth mode promoting radial growth of the semiconductor volume element.
