“…Dulot et al (2000) showed that the surface morphology of copper changes drastically upon repeated STM scanning even under standard tunneling parameters. Similar results were reported by Murphy et al (2003) on Fe surfaces. Although the above observations were accompanied by qualitative descriptions of possible surface diffusion aided by the strong electric field present between the STM tip and the sample surface, there was no attempt to develop a quantitative description of the phenomenon.…”

“…Observations of the influence of electric field on surface diffusion have so far been limited to STM tip-surface interactions (Avouris, 1995;Li et al, 1996;Dulot et al, 2000;Murphy et al, 2003), mainly as a means for single atom manipulation. This section presents an experimental investigation to demonstrate electric field induced bulk/continuum surface diffusion at micron and sub-micron scales.…”

“…There have been several articles reporting evolution of surface morphology under STM scanning (Avouris, 1995;Li et al, 1996;Dulot et al, 2000;Murphy et al, 2003). Avouris (1995) discusses several types of interactions between an STM tip and individual surface atoms by which the latter can be manipulated.…”

An experimental study of electric field induced surface diffusion is presented. A stability analysis of conductive surfaces subjected to a normal uniform electric field shows that sufficiently strong electric fields can destabilize a flat surface, similar to strain induced surface evolution in strain mismatched semiconductor thin films. Further, electric field gradients such as those under a sharp electrode or in the fringe field in a capacitor can drive surface diffusion, leading to nano-scale and micro-scale surface structure growth. Experiments are conducted on gold surfaces at elevated temperatures around 250-350°C, subjected to electric fields of the order of 10 8 -10 9 V=m. Growth of islands as ridges was observed, the height of which was as high as 200 nm. A description of the initial surface normal velocity is developed by using the MaxwellRowgoski solution for the fringe field at the edge of a parallel plate capacitor.

Appl. Phys. 98, 044910 (2005);We examine the thermodynamics and evolution of the morphology of a metal surface in the presence of a large electric field. A flat surface is unstable for all finite electric fields E with a critical wavelength proportional to E −1 or E −2 at small and large fields, respectively. The instability wavelength that grows the fastest during surface diffusion-limited evolution scales in the same manner. Such instabilities are important for scanning probe microscopies and are becoming increasingly important in microelectromechanical systems applications as device dimensions are reduced.

In this work we briefly review recent investigations concerning the growth morphology of thin metallic films on the Mo(110) and Ni3Al(111) surfaces, and Fe and copper phthalocyanine (C32H16N8Cu) on the Al2O3/Ni3Al(111) surface. Comparison of Ag, Au, Sn, and Pb growth on the Mo(110) surface has shown a number of similarities between these adsorption systems, except that surface alloy formation has only been observed in the case of Sn and Au. In the Pb/Mo(110) and Pb/Ni3Al(111) adsorption systems selective formation of uniform Pb island heights during metal thin film growth has been observed and interpreted in terms of quantum size effects. Furthermore, our studies showed that Al2O3 on Ni3Al(111) exhibits a large superstructure in which the unit cell has a commensurate relation with the substrate lattice. In addition, copper phthalocyanine chemisorbed weakly onto an ultra-thin Al2O3 film on Ni3Al(111) and showed a poor template effect of the Al2O3/Ni3Al(111) system. In the case of iron cluster growth on Al2O3/Ni3Al(111) the nucleation sites were independent of deposition temperature, yet the cluster shape showed a dependence. In this system, Fe clusters formed a regular hexagonal lattice on the Al2O3/Ni3Al(111).
