## Description

- description: We report on the impact of impurity doping on device performance enhancement
    of silicon quantum dot (SiQD) light-emitting diode. The increase in hole mobility
    resulting from boron doping increases the external quantum efficiency of electroluminescence
    by a factor of 12 and the optical power density by a factor of 2.65.
