摘要：

Optical properties of Si-doped GaInP grown on Ge-on-Si substrates were investigated using photoluminescence (PL). Similar to spontaneously ordered GaInP, two peaks were observed around 1.74 and 1.85 eV at 19 K; however, no satellite peaks were observed in the selected-area diffraction pattern. Based on temperature-dependent PL, the peak at 1.74 eV was attributed to the donor-acceptor pair transition caused by the amphoteric characteristics of Si and/or Ge from the dopant and/or substrate. In addition, the S-shape in the temperature dependence of the 1.85 eV peak was attributed to the interaction of the donor levels with the conduction band of GaInP.
