Light down-conversion with over 100% external quantum efficiency in bulk germanium

To bypass indirect bandstructure limitations in Ge and have it effectively emitting, we employ light down conversion process at elevated temperatures (emissivity enhancement technique). By applying short wavelength pump light ( lambda in, interband electron transitions), we enhance thermal emission...
