“…In the (simple) case that both the nominal and the facet surfaces are unreconstructed and show a (1 · 1) LEEDpattern, the observation of two successive intersections of the ''N'' and ''F'' LEED beams immediately provide this information as pointed out by Tucker [43]. However, this is only true if the bulk unit cell spanned by the nominal lattice and the facet is primitive one [45]. In this sense, the widely accepted derivation by Tucker, whereupon each intersection satisfies the depth condition, is incomplete and may lead to wrong conclusions if non-primitive bulk unit cells are considered as will be shown below.…”

“…The faceting of bcc͑111͒ metal surfaces covered with certain adsorbed gases has been known for years, [1][2][3] and more recent evidence has been found for faceting induced by ultrathin metal films. [4][5][6] Unlike the atomically smooth, closely packed, low-index substrates that comprise the majority of published studies on model thin film metal-on-metal systems, [7][8][9][10][11][12] bcc͑111͒ substrates represent atomically rough, morphologically unstable surfaces.…”

The faceting of Pd/W͑111͒ to form nanoscale three-sided pyramids with ͕011͖ facets has been observed using a scanning tunneling microscope ͑STM͒. In contrast to the well-documented ͕112͖ faceting, which can transform the entire Pd/W͑111͒ surface to a morphology composed completely of pyramidal ͕112͖ facets, the ͕011͖ faceting of Pd/W͑111͒ occurs in coexistence with ͕112͖ faceting upon prolonged annealing. While ͕112͖ facets are found to grow in size ͑ranging from ϳ3 to 15 nm͒ with increasing annealing temperatures, the dimensions of ͕011͖ facets appear to be limited to ϳ2.5 nm. The coexistence of two types of pyramidal facets is consistent with energetic considerations based on first-principles calculations. The difference in their typical sizes is, on the other hand, interpreted as an evidence for kinetic factors in the faceting processes.

“…The physical situation is directly analogous to the faceting of free surfaces where the surface can often reduce its energy by breaking up into a faceted structure consisting of relatively low energy facets (Herring 1951, Tracy andBlakely 1968).…”
