A systematic AFM study of gold films deposited on mica substrates under a range of selected conditions reveals the evolution of the surface morphology of the films as a function of growth temperature, film thickness, and deposition rate. Scaling analysis shows that the growth behaviour of the surfaces of these films can be considered as self-affine fractals. The observed topography follows island-type (3D) growth processes in the majority of cases with a roughness exponent, α, in the range 0.24-0.75, or quasi-2D island growth in the remainder with α = 1.19 or 1.45. In the latter cases, however, the two gold films grown under the particular conditions used reflect typical growth models expressing a high roughness exponent, well consistent with theoretical prediction.

An experimental electronic bandstructure of molybdenum disulphide has been determined from angle-resolved ultraviolet photoelectron spectroscopy (ARUPS) measurements: polar-angle-dependent ARUPS at a photon energy of 21.2 eV allows the authors to obtain an approximate plot of dispersion parallel to the basal face while photon-energy-dependent ARUPS at normal emission gives a plot of dispersion perpendicular to this face. The experimental bandstructure is compared with three calculations and, while there is a general agreement, specific aspects are better reproduced when there is self-consistency in the calculations. An analysis difficulty reported earlier for polar angle ARUPS for this material can now be understood as arising from incorrect labelling of symmetry directions in the experiment.
