Abstract :
We present a polarization resolved near edge X-ray absorption fine structure (NEXAFS) investigation of ethylene (C2H4) adsorbed on the oriented single-domain Si(0 0 1)-(2 × 1) surface.
he detected resonances and their polarization dependences C2H4 is found to be strongly bound to the silicon dimers with the carbon atoms in a sp3-hybridized state. The molecular axis is rotated around the surface normal with respect to the dimer axis.
