Abstract

Nd-doped semiconductor light-emitting diodes were fabricated by implanting Nd ions into a GaAs epi-layer. The fabricated GaAs:Nd diodes show good current-voltage characteristics with a typical reverse breakdown voltage between 8 and 12 V. By injecting minority carriers into the diodes, Nd³⁺ related emissions were observed, at 77 K, in the 0.92, 1.11, and 1.3 μm regions. These electroluminescence signals correspond to the transitions from Nd³⁺ ⁴F_3/2 state to the Nd³⁺ ⁴I_9/2, ⁴I_11/2 and ⁴I_13/2 states, respectively. The measured external quantum efficiency of the GaAs:Nd diodes at 77 K, was 5×10^-7.
