Complete crack elimination in strained SiGe/Ge(111) heterostructures by pre-patterning of Si(111) substrates

We propose a novel method to completely eliminate cracks, which are unavoidably generated in strained SiGe(111) layers grown on Ge(111). We perform mesa-patterning of the Si(111) substrate first, and subsequently grow the strained SiGe/Ge(111) on the pre-patterned Si. It is resultantly demonstrated...
