  • Strain-balanced semiconductor structure
    Patent number: 11005231
    Abstract: Systems and methods are described herein to grow a layered structure. The layered structure comprises a first germanium substrate layer having a first lattice constant, a second layer that has a second lattice constant and is epitaxially grown over the first germanium substrate layer, wherein the second layer has a composite of a first constituent and a second constituent, and has a first ratio between the first constituent and the second constituent, and a third layer that has a third lattice constant and is epitaxially grown over the second layer, wherein the third layer has a composite of a third constituent and a fourth constituent, and has a second ratio between the third constituent and the fourth constituent, wherein the first ratio and the second ratio are selected such that the first lattice constant is between the second lattice constant and the third lattice constant.
