Adsorption and desorption of hydrogen on Rh(311) and comparison with other Rh surfaces

We present LEED and thermal desorption data for hydrogen adsorption on Rh(311). An anisotropic lattice gas model with first, second and third nearest neighbor and trio interactions is set up and solved using transfer matrix techniques to explain equilibrium structural data and temperature-programmed...

Description
Summary:We present LEED and thermal desorption data for hydrogen adsorption on Rh(311). An anisotropic lattice gas model with first, second and third nearest neighbor and trio interactions is set up and solved using transfer matrix techniques to explain equilibrium structural data and temperature-programmed desorption consistently. A comparison with results for hydrogen on Rh(110) and Rh(111) is made.
