  • Heterojunction semiconductor device with <001> tilt
    Patent number: 4872046
    Abstract: A method is disclosed of epitaxially depositing a semiconductor material on a substrate of different material while accommodating lattice mismatch in a manner that results in improved epitaxially deposited material. In a disclosed embodiment GaAs is epitaxially deposited by molecular beam epitaxy on a silicon substrate having a {100} crystallographic surface tilted in the <001> direction. Improved semiconductor devices, made using the disclosed technique, are also set forth.
