“…were also in agreement with reported results [ 1,6,10,11]. It is worth noticing that our bestfitting parameters are quite close to those recently reported by Yeh et al [6] and Molodtsov et al [ 111 for the Au/Si( 111) interface grown at room temperature.…”

Spectromicroscopy of the metastable interface studied by means of synchrotron radiation

The thermally agglomerated Au/Si( 111) interface has been studied by means of laterally resolved photoemission by exploiting the ultra-high brightness of the ELETTRA synchrotron radiation source. The interface has been evaluated in terms of chemical maps and core level spectra acquired from selected points of the specimen surface. The variety of distinct chemical environments local to element-specilic sites has thereby been clarified with an unprecedented level of resolution at both the islands and the two-dimensional superstructure terminating the Si crystal.

“…In spite of the immiscibility established by bulk thermodynamics in the solid state binary alloy [4], metastable pseudo-silicides are found for ultrathin Au films deposited on top of atomically clean Si substrates [ 1,3,5,6]. This unexpected chemical reactivity has been demonstrated to be acting even at low temperatures.…”

“…39,40 Our structural relaxations give an optimal geometry with d = 2.30Å, in agreement with previous results. 28 Using the relaxed geometry as a reference, we construct additional structures by increasing the distance to 3.0, 3.5, and 4.0Å.…”

We investigate the electronic structure and electron transport properties of Si nanowires attached to Au electrodes from first principles using density functional theory and the nonequilibrium Green's function method. We systematically study the dependence of the transport properties on the diameter of the nanowires, on the growth direction, and on the length. At the equilibrium Au-nanowire distance we find strong electronic coupling between the electrodes and nanowires, which results in a low contact resistance. With increasing nanowire length we study the transition from metallic to tunneling conductance for small applied bias. For the tunneling regime we investigate the decay of the conductance with the nanowire length and rationalize the results using the complex band structure of the pristine nanowires. The conductance is found to depend strongly on the growth direction, with nanowires grown along the 110 direction showing the smallest decay with length and the largest conductance and current.

“…It has been shown that despite the fact that Au is a very stable and unreactive noble metal, it is very reactive on Si surfaces even at room temperature. [23] Several metastable Si-Au alloys, including a [SiAu 4 ] phase, have been observed to form in the Si-Au interface. [24] However, the nature of the chemical interactions between Au and Si in the Si-Au interface is still not well understood.…”

Gold is isolobal to hydrogen. Despite the fact that Au and Si do not form stable alloys, Si and Au form stable covalently bounded clusters, as evidenced from anion photoelectron spectroscopy and ab initio calculations. In a series of [SiAun] clusters (n=2–4) that are similar to SiHn (n=2–4) in structure, chemical bonding, and stability, Au atoms are shown to be isolobal to hydrogen atoms (see picture).
