  • Depositing polar materials on non-polar semiconductor substrates
    Publication number: 20070238281
    Abstract: Lattice mismatch and polar to non-polar issues may lead to dislocations and other defects between silicon or germanium substrates and group III-V materials such as indium antimonide. The provision of lattice matching layers and buffer layers may enable these defects to be reduced.
