Abstract

We have studied the crystallinity and Schottky diode characteristics of GaAs/Si grown by MOCVD. In comparison with two-step growth and GaP/strained layer superlattice techniques, the crystallinity and the Schottky diode characteristics are superior for the GaAs/Si with Al0.5Ga0.5P as an intermediate layer. The GaAs/Si grown with the Al0.5Ga0.5 intermediate layer shows mirror—like surface morphology and an X-ray FMHM of 188 arcs. The ideality factor of the Schottky diode fabricated on the GaAs/Si grown with the Al0.5Ga0.5P intermediate layer is 1.06, but its forward current-voltage characteristic shows a significant leakage current at small forward bias. It is also found that the composition of Al affects strongly the crystallinity and the Schottky characteristics of GaAs/Si.
