Scanning tunneling microscopy and X-ray photoelectron spectroscopy of silver deposited octanethiol self-assembled monolayers

Alloying process at the interface of silver nanoparticles deposited on Au(111) substrate due to the high-temperature treatments

“…When almost all atoms of silver leave the surface the C 1s line stops shifting and its maximum is located at 284.1 eV. Very similar results are reported for the thiols deposited on silver and gold surfaces [30,31] where the shift of C 1s line is estimated as 0.6 eV. In the present experiment the shift is in a similar range of order.…”

Deposition of Ag nanoparticles on fluoroalkylsilane self-assembled monolayers with varying chain length

“…Obviously the morphology is directly influenced by the amount of the deposited silver (see e.g., [17,20,25,42]). To verify that the same stage of film growth is compared the deposited silver of the investigated samples was dissolved in a hydrogen peroxide and ammonia solution.…”

“…The functional molecules of the organic film can be deposited by means of selfassembly or by the Langmuir-Blodgett film technique and the top contact by means of metal evaporation. The interactions between SAMs and deposited metal over layers certainly influence electronic properties and the function of the devices [24,25]. In this context FAS monolayers are attractive because of their simplicity of preparation and because their film thickness can be precisely controlled by changing the length of the fluoroalkyl chain.…”

Electrochemical Metal Deposition on Top of an Organic Monolayer

“…In this geometry, a Au substrate usually serves as a bottom electrode. The top electrode could be metal nanoclusters prepared by vacuum vapor deposition [1][2][3][4][5][6][7][8][9][10] or from a suspension of metal nanoparticles. [11][12][13][14] Previous studies have shown that vapor-deposited Au or Ag penetrates into the SAM and inserts into the thiol-Au bond at the Au/ SAM interface when it is vacuum-deposited on an alkanethiol SAM with a methyl end group.…”
