摘要：
We repeat a calculation we previously performed on the unreconstructed Ge6(GaAs)3 (001) super-lattice using a Gaussian-orbital expansion; this time the calculation is performed on Ge8(GaAs)4 (001) using a plane-wave expansion in order to make comparisons with previous calculations on reconstructed Ge8(GaAs)4 more meaningful. We find the reconstruction reduces the formation enthalpy by 191 meV per unreconstructed unit cell.
