Abstract
A light emitting field effect transistor is proposed with a new extended drain region. The extension is doped with erbium or other rare-earth atoms. The erbium provides light-emitting centers in the indirect bandgap silicon substrate to enhance the radiative process. When a drain voltage is applied to create a high enough electric, energetic electrons entering this region interact with Er to emit infrared light.
