First Principles Calculations of Charge and Spin Density Waves of sqr3-Adsorbates on Semiconductors

S. Scandolo, F. Ancilotto, G. L. Chiarotti +3

We present ab-initio electronic structure results on the surface of sqr3 adsorbates. In particular, we address the issue of metal-insulator instabilities, charge-density-waves (CDW…
