Mixed Ge-Si Dimer Formation in Ge/Si(100) and Si/Ge(100) Growth

Abstract

Properties of (skew-symmetric) conformal Yano-Killing tensors are reviewed. Explicit forms of three symmetric conformal Killing tensors in Kerr spacetime are obtained from the Yano-Killing tensor. The relation between spin-2 fields and solutions to the Maxwell equations is used in the construction of a new conserved quantity which is quadratic in terms of the Weyl tensor. The formula obtained is similar to the functional obtained from the Bel-Robinson tensor and is examined in Kerr spacetime. A new interpretation of the conserved quantity obtained is proposed.
