Abstract
The present disclosure relates to a semiconductor structure and a method of preparation including a silicon monocrystalline substrate, and a III-V structure abutting the silicon monocrystalline substrate. The semiconductor structure includes an InGaAs structure overlaying the III-V structure, where a is from 0.40 to 1, b from 0 to 0.60, and a+b equal to 1.00. The III-V structure has a top surface facing away from the silicon substrate. The top surface is GaXPSbZ, where X includes one or more group III elements other than Ga and Z is one or more group V elements other than P or Sb. g is from 0.80 to 1.00, x is from 0 to 0.20, z is from 0 to 0.30, p is from 0.10 to 0.55, and s is from 0.50 to 0.80, g+x is equal to 1.00 and p+s+z is equal to 1.00.
