  • Ge-Si quantum well structures
    Patent number: 7599593
    Abstract: Si—Ge quantum wells where the well material has a lowest conduction band energy minimum at k=0 (the ? point of the first Brillouin zone) are provided. Quantum well structures that satisfy this condition have “Kane-like” bands at and near k=0 which can provide physical effects useful for various device applications, especially optical modulators. In the Si1?xGex material system, this condition on the band structure is satisfied for x greater than about 0.7. The quantum well barrier composition may or may not have Kane-like bands. A preferred method of providing such quantum well structures on a substrate (e.g., a silicon substrate) is to grow a first Ge-rich Si—Ge buffer layer on the substrate, and then anneal the resulting layered structure. In many cases it is further preferred to grow a second Ge-rich Si—Ge buffer layer on top of the first buffer layer and anneal the resulting layered structure.
