“…As was discussed above, many basic physical properties, between them density, is not constant and they depend on cluster size in nano-region [10][11][12][13] . Due to this, we calculated density of gold depending on size of nano-structures and we compared it with experimental data.…”

“…However, it is well known that the properties of gold vary depending on their size in the range of nano-dimension rapidly due to the so called surface size and quantum size effects 8,9 . Also different arrangement of Au crystal lattice, lattice parameter values and a certain volume disorder play an important role in property changes of nano-sized materials [9][10][11][12][13][14][15] . Both the size effects and the different arrangement of crystal lattice result in that gold nanoparticles exhibit different values of many physico-chemical properties in contrast to the bulk.…”

Firstly, I would like to say, this contribution is written only for this Dedicated Issue of CCCC, only for my sweet boss, dear friend and my heavy criticZrzek. Time to time I attended some conferences focused on modeling, simulations and I understood this point badly. Many renowned professors spoke about some playing with balls and only gradually I have found out that "playing with small balls" could be useful, important and had many applications. To delight my dear Zrzek, I started to look intensively for some suitable "ball problem" for me. Thanks to my dear colleagues, co-authors of this paper, I got a chance for "balling". I have chosen the special problem of gold nano-clusters and nano-layers sputtered on solid surfaces.The gold density enters some indirect determination of gold properties as an input parameter. Reported gold density of 19 320 kg m -3 at standard conditions is correct for gold bulk or macro-sized specimens. For nano-sized specimens (nano-clusters, nano-layers), however, this standard density value need not be applicable. This work deals with gold density as a function of the nano-structure size. The calculated density was compared with experimental one performed for gold sputtered onto glass or poly(ethylene terephthalate) substrates. Calculated gold density was found to increase from 11 249 to 19 304 kg m -3 when the characteristic dimension of gold nano-structures increases from 0.7 to 82 nm. At the same time the free volume fraction in nano-structures decreases from 57 to 26%.Vacuum-deposited metal clusters and thin films play an important role in various fields of technology 1 . Gold in the form of thin films is nowadays used in a vast range of applications such as micro-and nano-electromechanical systems (MEMS and NEMS) 2 , sensors 3 , electronic textiles 4 , bioengineering 5 , generators of non-linear optical properties 6 or devices for surface-enhanced Raman scattering 7 .

Thin palladium films are deposited on boron‐doped p‐type Si(111) single crystals under UHV conditions. The structure is studied in situ by LEED and Auger analysis, in addition the resistivity is measured with the help of a four‐probe technique. The resistivity always decreases with increasing film thickness. For films deposited on an oxygen‐free silicon surface with a 1 × 1 structure, the decrease mainly occurs at very low thicknesses, then the resistivity approaches a saturation value which is characteristic of a layer‐by‐layer growth. For films deposited on silicon with oxygen present in the surface, a steep decrease is observed at much higher thicknesses. Island growth is then the dominating factor for the conduction behaviour.

The structure of epitaxially grown ultra-thin gold films is investigated by x-ray diffraction, texture analysis and LEED/Auger techniques. High sensitivity of the x-ray diffraction analyzer has been achieved by means of a step scanning unit and an impulse height discriminator. The resolving power is then sufficient for the detection of the reflections of films as thin as 1 nm. It is concluded that the particle size broadening is the limiting factor for a further extension of the investigation range towards smaller thicknesses.
