Structure determination of the (3sqrt{3}x3sqrt{3}) reconstructed alpha-Al_2O_3(0001)

Igor Vilfan, Thierry Deutsch, Frederic Lancon +1

Grazing-incidence X-ray diffraction data are combined with energy-minimization calculations to analyse the atomic structure of the Al-rich (3sqrt{3} x 3sqrt{3})R 30 deg reconstruct…
