Abstract

We have studied the properties of $GaAs_{1-x}P_x$ epitaxial films on the GaP using VPE method by CVD. The surface carrier concentration and PL power increased with increasing the epitaxial temperature while PL wave length decreased. The Power out of the LED with $GaAs_{1-x}P_x$/GaP structure decreased with increasing the epitaxial temperature while the forward voltage of the LED increased. Specially, The LED of $GaAs_{1-x}P_x$/GaP structure represents good electrical and optical properties when the $GaAs_{1-x}P_x$ layer was epitaxially grown at $810^{\circ}C$.
