Abstract
A semiconductor light emitting device () comprises a semiconductor structure () comprising a first body () of a first semiconductor material (in this case Ge) comprising a first region of a first doping kind (in this case n) and a second body () of a second semiconductor material (in this case Si) comprising a first region of a second doping kind (in this case p). The structure comprises a junction region () comprising a first heterojunction () formed between the first body () and the second body () and a pn junction () formed between regions of the structure of the first and second doping kinds respectively. A biasing arrangement () is connected to the structure for, in use, reverse biasing the pn junction, thereby to cause emission of light.
